ExplorerFocus
A file explorer · WPF · .NET 10

Windows Explorer,
without the noise.

ExplorerFocus is a Windows Explorer replacement for people who always work in the same folders. Configurable profiles, clean trees, a preview that opens almost anything — code, documents, books — and operations that actually tell you what's happening. Without the shell's noise.

Which one? The .exe is the usual download; the .zip is for organisations that block .exe downloads.

Version history

✦ What's new v2.2.2
§ 01 · Listen and writeFreePREMIUM

One translator for everything.

ExplorerFocus now listens: it writes down what is said in audio and video files, and translates what is said, subtitles, a video as it plays, PDFs and books. All on the computer itself. The translation is automatic, and worth reviewing.

SUBTITLES

In the language you want.

Create subtitles… listens to the video and writes the subtitles with their timings, in the spoken language or translated. Translate subtitles… turns an .srt into another language. They are saved next to the video, and the preview and players such as VLC find them on their own.

LIVE

While the film plays.

In the preview, a film in another language gets translated subtitles without stopping. Also inside a vault.

IN BATCH

A whole series at once.

Create subtitles in batch… subtitles every episode, in English and in the chosen language, while you do something else. Stopping halfway loses nothing: it carries on from where it stopped.

TRANSCRIBE AND DICTATE

From sound to text.

The text of a recording, as text, Word, PDF or subtitles — even when more than one language is spoken. And on the 🎤, Record and transcribe writes down what is said, as you speak.

PDF AND BOOKS

A whole book in another language.

A PDF, scanned ones too, or a book in EPUB, PDF or FB2, translated into another language. A long job can be paused and continued later.

ON THE COMPUTER ITSELF

Nothing leaves it.

The ear and the translator come once, only with permission, and serve every language. After that, the sound, the text and the translations stay on the computer, and no internet is needed. With a graphics card, much faster.

Free: dictating to .txt, on the 🎤. PREMIUM: subtitles, live subtitles, the batch, transcribing to Word, PDF and subtitles, and every translation.

§ 02 · Catalog

What really
makes a difference.

Each feature was added to answer a concrete problem in daily work over a known file tree. None is there for show. Almost all can be toggled on or off.

01 — PROFILESFree

Multi-tab by context. Each profile is its own view, with its tree, filters and state.

Drag-reorder, F2 to rename, Ctrl+1..9 to jump between tabs, Ctrl+T to create. Tabs remember the last folder visited and the tree state.

tabs · ● default · ○ scripts · ○ research active ← highlighted in amber ● included in global search
02 — TREESFree

Configurable trees.

You manually define the roots you want to see. Filesystem and registry side by side. No sidebar full of items you never open.

Folder + Registry
03 — SEARCHFree

Multi-pattern search with wildcards in any position.

Type *.cs *.json and get OR semantics. ?onfig.json, Test*Run.cs — all work.

Wildcards · Internal regex
04 — GLOBAL SEARCHFree

Search across profiles, with explicit opt-in.

Right-click a tab → "Include in global search". The dot indicator (●/○) shows what's in. The results open right in ExplorerFocus — in this window or a new one, on the chosen file.

Opt-in · Opens here or in a new window
05 — PREVIEWFree

Rich preview pane. Each file type with its ideal rendering.

Text with syntax highlight via AvalonEdit, images decoded in the background, PDFs rendered by the Edge engine (WebView2), Markdown converted to HTML with a dark theme by Markdig. Individually toggleable. Cancels previous load if you change selection.

SOURCE · MainViewModel.cs · C#

MARKDOWN · README.md

ExplorerFocus

A focused Windows Explorer replacement. Built around configurable folders, it forgets everything that doesn't matter.

net10.0-windows · WPF · single-file

Note — preview works with Edge WebView2 installed (ships with Windows 10/11).

06 — FILE OPERATIONSFree

Copy, move, delete — with real information.

Floating window shows per-file gauge, real speed, ETA, global count. Pause, resume, cancel. Up to 6 parallel operations. Get on with your life while it runs.

Buffer 1 MB · 10 Hz UI · history × 20
07 — CONFLICTSFree

6-way.

Overwrite / Skip / Duplicate, individually or in bulk for the rest of the operation.

08 — DRAG & DROPFree

Between tabs.

Drag a file to a tab and the tab switches on its own after 600ms. Copy/Move dialog on drop.

09 — APPS BY EXTENSIONFree

Auto-detect new extensions. Shared across profiles.

Enter a folder with .dwg, .psd, .bak? An aggregated dialog asks once. Per-row picker (browse to the .exe; name auto-resolved by FileVersionInfo). Mark as ignored those you don't care about. The list persists.

Mute per session · Toggle in Settings
10 — TERMINALSFree

CMD, PowerShell, Git Bash — here, now.

In any tree folder. Normal and elevated variants. regedit on registry keys.

11 — CREATE FILESFree

Sensible skeletons.

.cs, .xaml, .json, .md, .cmd, .ps1 — start with the typical structure. The name is highlighted without erasing the extension while typing.

12 — DARK OR LIGHTFree

Dark or light, instantly.

One button, next to PREMIUM: dark, light or like Windows, without restarting. In light mode, two sliders set the white of the background and the darkness of the text. Each window keeps its own.

13 — PERSISTENCEFree

Remembers everything.

Geometry of the main window and the operations window. Last active tab. Tree pane width. Column sort. Tree state. All in %LOCALAPPDATA%\ExplorerFocus.

14 — RICH TOOLTIPFree

Properties without a click.

A 1.8s tooltip over any file shows computed size, dates, attributes. Folders carry the recursive size — computed lazily, with a semaphore to avoid hammering the disk.

15 — SORTINGFree

Folders first, always.

A custom comparer guarantees directories stay on top of any sort, in any column, in any direction. As it should be.

16 — MULTI-SELECTFree

Smart selection.

Normal click selects. Shift+click extends with "majority decides" semantics — if the range is mostly already selected, it unmarks; otherwise it marks. Ctrl+click toggles individually. No more "I lost all selections by accident".

17 — DEPLOYMENTFree

A single .exe. No installer.

Self-contained, single-file, compressed and digitally signed. Copy to a flash drive and it runs on any 64-bit Windows 11. It also runs on Windows 10 version 1809 or later, without support. No .NET to install. net10.0-windows + WPF — no dependencies outside the executable's folder.

18 — 16 LANGUAGESFree

The whole app, in sixteen languages.

Not just the menus — every dialog, every message, every tooltip. Pick one and the interface changes on the spot: nothing to restart, nothing to reinstall.

Português Português (BR) English (GB) English (US) Español Français Italiano Deutsch Polski Русский العربية हिन्दी 中文 (简体) 中文 (繁體) 日本語 한국어
19 — THE DISK, IN DETAILFree

Click a disk and it says exactly what it is.

Manufacturer, model, firmware and serial number. Platter or solid state — and it says which, because a platter pays a seek penalty. Bus, sector size, partition scheme, the device underneath. What the file system really supports: EFS, per-file compression, hard links, junctions and symbolic links, sparse files, quotas, ACLs, the USN change journal, case sensitivity. And SMART data, when the disk gives it.

Manufacturer · Model · Firmware · Serial · SMART · GPT/MBR · Sector size
20 — MY MACHINEFree

Everything the machine knows about itself — and never shows.

Firmware identity and serial numbers, when the machine was built, what is soldered to the board, the memory slot by slot, and how Windows was installed. Read-only: it never goes online and never asks for elevation.

SMBIOS · Firmware · Memory · Devices · Windows install
21 — TASK MANAGERFree

Which program is holding this file?

Windows says the file is open somewhere and never says where. This one knows, because it lives inside the explorer. It also answers three questions the system's own manager doesn't: what runs from your user folder, what is not signed, and which of two copies of the same program is which version. Ending a process asks first — with the name, the PID and the window title — and the ones that would blue-screen the machine have no button at all.

Who's holding it · AppData · Unsigned · Version
22 — REMOTE ACCESSFreePREMIUM

SFTP, FTP/FTPS and WebDAV — the explorer reaches the server.

Connect to SFTP, FTP/FTPS and WebDAV (Nextcloud, ownCloud, NAS, IIS). Browse, preview, upload and download, create folders, rename and copy/move — with byte-level progress and cancel. Edit remote files locally and sync on save. Password or SSH key auth; secrets encrypted with DPAPI.

SFTP · FTP/FTPS · WebDAV

Free: 1 SFTP/FTP/FTPS connection — browse and preview only. PREMIUM unlocks WebDAV, multiple connections and all operations.

23 — CLOUDSPREMIUM

Dropbox and OneDrive — your cloud inside the explorer.

Connect to Dropbox and OneDrive via secure OAuth — no passwords stored. Browse, preview, upload and download, create folders, rename and copy/move, like a local folder. Your files never pass through our servers.

Dropbox · OneDrive

PREMIUM: required from the first connection — browsing, preview and all operations.

24 — BOOKS & COMICSFreePREMIUM

Eight book formats — preview and read, without leaving the explorer.

Instant preview of any .epub, .mobi, .azw, .azw3, .prc or .fb2: cover, table of contents and the opening text. Open the full book in its own reader, with chapter navigation, page jump, auto-scroll and your reading position remembered. Comics too: .cbz and .cbr open page by page, without unpacking hundreds of megabytes first.

Paper mode. The same book, another look: two facing pages, the spine down the middle, paper with grain and lamp light, and the sheet folding under your hand as it turns. One button cycles plain · paper · night paper, and plain stays the default. It does not become a real book — no texture, no sound of the page, no smell, none of the weight of picking it up and putting it down — but a screen can come close. What that buys is comfort, and comfort is personal: everyone reads better in their own way. This is simply one more.

The E-books button. Select a book and the E-books button lights up at the top: open it in the reader, convert it between EPUB, PDF and FB2, or translate the whole book. Comics (CBZ, CBR) become a PDF or a fixed-layout EPUB, and a PDF becomes an e-book, with the chapters from its bookmarks.

EPUB · MOBI · AZW · AZW3 · PRC · FB2 · CBZ · CBR

Free: preview — cover, contents and a first look inside.
PREMIUM: full reader — navigation, page jump, auto-scroll, paper mode, page-turn and memory of your last 20 books — and the E-books button. Books you own open. Books bought with DRM stay locked to the store that sold them — the app explains why when it finds one.

25 — DOCUMENT VIEWERSFree

Word, Excel, PowerPoint and more — see without opening anything.

Preview Word (.doc/.docx), Excel, PowerPoint, RTF and OpenDocument (text, sheet and presentation) right in the pane. Audio and video play in the preview, with a floating window and volume/speed controls. A marker flags files that have a preview; password-protected files are flagged without asking for the password.

Word · Excel · PowerPoint · RTF · OpenDocument · Audio · Video
26 — RECORD AUDIOFree

Record the microphone straight into the folder.

One click records the microphone into the current folder. Pick the microphone, watch the live level meter, adjust the recording volume and save as MP3, AAC, WMA, WAV, FLAC or ALAC.

Microphone · Level meter · MP3 · AAC · WAV · FLAC
27 — RECORD VIDEOFreePREMIUM

Record the camera straight into the folder.

Live camera preview, with a choice of camera and microphone, resolution and format — MP4, WMV or AVI. Saves into the current folder with one click.

Camera · Microphone · MP4 · WMV · AVI

Free with a discreet footer watermark. PREMIUM: no watermark.

28 — SCANFreePREMIUM

From the scanner into the folder — image or PDF.

Scan from the flatbed or the feeder (ADF), many sheets at once. Choose the resolution and colour — colour, grayscale or black & white. Save as JPEG/PNG or merge everything into a multi-page PDF, and keep adding sheets to the same PDF.

Flatbed · Feeder (ADF) · Colour · Multi-page PDF

Free: 1 flatbed page, with a watermark. PREMIUM: multiple pages, feeder (ADF) and no watermark.

29 — ARCHIVES AS FOLDERSFree

Open ZIP, RAR, 7z and TAR like folders.

Double-click (or Browse inside) to enter the archive — browse the contents, preview and copy files out without extracting everything. Read-only; Open with… still opens them in WinRAR/WinZip/7-Zip.

ZIP · RAR · 7z · TAR · Copy files out
30 — RECORD SCREENFreePREMIUM

Record the screen straight into the folder — with an optional camera.

Pick a region of any monitor (or the whole screen) and record to MP4 with the microphone. Add the camera: switch screen⇄camera with transitions (fade, wipe, slide, mosaic), show it as PiP in a corner, or side by side in split screen.

Region · Microphone · System sound · Camera · PiP · Split screen · Transitions · MP4

Free: watermark + 15 s and no sound. PREMIUM: no watermark, no time limit and with sound (microphone + system).

31 — BRANDING CARDSPREMIUM

Intro and end cards for your videos — right in the recording.

Give your recordings (screen and camera) an intro card, a permanent text banner and a credits-style end card (up to 10 lines). 5 independent models, each with 3 presentations, logo, background colour and an episode badge — built for a consistent video series.

Intro · Banner · End (credits) · 5 models · Logo · Episode badge

PREMIUM. Discreet “Made with ExplorerFocus” signature on the end card.

32 — VOICE OVERFreePREMIUM

Narrate your videos after recording — even on your own.

Record the screen silently, then in a dedicated box play the video while you narrate over it. The narration lands in a separate file; add background music, balance the volumes (so the music won't drown the voice) and generate the final video with all three sources.

Record silent · Narrate over the video · Music · Volumes · Video + narration + music → final

PREMIUM. The video and narration stay as separate files; only “Generate final” creates the mixed video.

33 — AUDIOFreePREMIUM

Cut, split and join audio — without opening an editor.

Select an audio file and the Audio button lights up at the top. Cut a section while listening, split it into parts at the points you mark or into equal parts, join several into one — even of different formats — and change format in one click: MP3, AAC, WMA, WAV, FLAC or ALAC. MP3 tags (title, artist, album and cover) are written into the file itself, without touching the sound. In Adjust the audio…: the volume and normalize, the speed without changing pitch, fade in and out, trimming the silence at the start and end, and shortening the pauses of a voice recording. The original stays as it is.

X-ray and transcription. The Audio X-ray… shows the format, the channels, the tags and every metadata field, and Transcribe… turns a recording into text.

Cut · Split · Join · Change format · MP3 tags · Volume · Speed · Silence · Pauses · X-ray · Transcribe

Free: cut, split, join, change format, MP3 tags and the Audio X-ray.
PREMIUM: Transcribe… and Adjust the audio… Both open for everyone: you see and hear what they do before you have PREMIUM.

34 — VIDEOFreePREMIUM

Cut, rotate, shrink and adjust videos — right where they are.

Select a video and the Video button lights up. Cut a section or take one out of the middle, split into 30-second parts for statuses and stories, join several into one, rotate a video filmed sideways — an MP4 without losing any quality — and save a frame as a JPG without stopping the video. The video's sound goes out to MP3, AAC, WMA, WAV, FLAC or ALAC, or you keep a copy without sound. With PREMIUM: convert or shrink to fit WhatsApp — the box tells you how big it will be before converting — a light GIF of a section, the video in reverse, add a sound (music or narration), and Adjust the video…: colours and black and white, speed from 0.25× to 4× without the voice changing, fade in from and out to black, the volume, the 9:16 crop for social media, the mirror and the watermark — all in one pass, and seen before saving. The original stays as it is.

X-ray, 5.1 and subtitles. The Video X-ray… says everything the file contains and, when it won't play on this computer, why and what to do. In a 5.1 film, Audio 2.0 puts the voices on both speakers while you watch, and Convert the sound to stereo saves a copy that way. Subtitles that come with the video show in the preview; to create and translate them, see Listen and write.

Cut · Split · Join · Rotate · Frame · Sound → MP3/FLAC · Convert · GIF · Colours · Speed · 9:16 · Watermark · X-ray · Audio 2.0 · Stereo · Subtitles

Free: cut, split, join, rotate, save a frame, the video's sound, the Video X-ray, Audio 2.0 and watching subtitles.
PREMIUM: convert or shrink, GIF, Adjust the video…, reverse, add a sound and convert the sound to stereo. Also inside a vault: the result is born in there, encrypted, and nothing is left in the clear on the disk (saving the sound as FLAC is the exception, and the app explains why).

35 — IMAGEFreePREMIUM

What a photo carries hidden — and the tools to deal with it.

Select an image and the Image button lights up. Photo X-ray shows what it carries hidden — where it was taken, the camera and its serial number, the dates, and the hidden thumbnail that sometimes still shows what was cropped out — and saves a copy with only what you choose. It also says whether the image declares it was made or edited with AI, and with which program, and Near… names the town without going online. Then: crop and straighten a crooked horizon, shrink to send to the size you want, rotate and flip — a JPG without losing any quality — change format (iPhone HEIC to JPG in one click, and even Windows .ico icons), copy the image to paste it into WhatsApp, and Ctrl+V in a folder turns a screenshot into a file. With PREMIUM: copy the text from an image, cover what's private (emails, phone numbers, IBANs, cards and faces), join and split images, and the transparent background. The original stays as it is.

X-ray · AI mark · Near… · Crop · Shrink · Rotate · HEIC → JPG · ICO · Copy · Ctrl+V · Text · Cover · Join · Split · Transparent background

Free: the X-ray, crop, shrink, rotate and flip, change format (with ICO), copy, and paste as a file.
PREMIUM: copy the text, cover what's private, join, split and transparent background. No AI mark doesn't mean the image is real: many don't carry one. Cover finds a lot, but always check before sending. Show on map… asks first, because then the coordinates go to OpenStreetMap. Place names come from GeoNames (geonames.org), CC BY 4.0 — the full credit is under Stack.

36 — PDFFreePREMIUM

Merge, split and tidy up PDFs — right where they are.

Select a PDF and the PDF button lights up at the top. Merge several into one, split by page ranges (1-3, 5, 8-), or organize the pages on thumbnails: rotate, delete, reorder, or pull a few out into a new PDF. Turn pages into JPG or PNG images, add or remove a password, and convert JPG/PNG images and simple Word documents to PDF — or put several photos on one A4 page, in the order of the list, seeing the PDF on the right as it will be, page by page. The original is never touched: every result is a new PDF right beside it, with its bookmarks and document details carried over. Nothing is uploaded anywhere.

X-ray, text and translation. The PDF X-ray… shows the pages, the text, the protection, the fonts, the forms, the signatures, the attachments and the JavaScript. Recognize the text (OCR)… makes a scanned PDF searchable and copyable, Translate the PDF… puts it into another language, and Convert to e-book (EPUB, FB2)… turns it into a book that flows.

Merge PDF · Split PDF · Rotate & reorder pages · PDF to JPG/PNG · Password-protect or unlock PDF · Word & JPG to PDF · Several photos per A4 page · PDF X-ray · OCR · Translate PDF · PDF to e-book

Free: merge, split and the PDF X-ray.
PREMIUM: organize pages, PDF to images, add or remove a password, convert to PDF (several photos per page too), recognize the text, translate and turn into an e-book. A password-protected or damaged PDF is reported, and nothing half-made is left behind. Works inside an encrypted vault too, through its drive letter.

§ 03 · The vaultPREMIUM

Encrypted, and still just folders.

A vault is a set of encrypted files on disk — file names, folder names and contents, all of it. Open it with your password and the tree, the preview, the search and the file operations work exactly as they always did, over content decrypted on the fly. Close it, and what is left on the disk is unreadable names and bytes without meaning.

A padlock
ONE, OR A THOUSAND

Vaults are objects

A vault is a branch like any other — put one on a disk, or a hundred, side by side with ordinary folders. Each carries its own password. A single gesture opens every vault that shares one, whether that is one vault or a thousand, and a single gesture closes them all.

48 WORDS

The only other way in

Each vault makes its own 48 words when it is created — its key, in plain language. The password or those words: nothing else opens a vault. We cannot open it either — lose both and the vault is gone. Keep the words where the vault is not.

A DRIVE LETTER

Open to every app

Give a vault a drive letter and it becomes an ordinary drive for everything on the machine — ffmpeg, Word, WinRAR and the explorer's own recorder write straight into it. Mounting trades secrecy for compatibility, which is why it is never the default.

NO WAITING

Read and play inside

Files are encrypted in blocks, not as a whole. A 4 GB video never has to be decrypted into memory first — the preview opens, and you can jump straight to minute forty. Documents, books and images preview the same way, inside the vault.

VAULT SIZE

As big as its disk

There is no limit of ours. A vault holds a single file, or several TB across thousands of them. It stops where the disk stops.

FILE SIZE

Whatever the disk allows

16 TB on NTFS, 16 EB on exFAT — and 4 GB on FAT32, because that is FAT32's limit and not ours. Encryption adds about 0.09%, so a file that only just fits stops fitting: the check runs against the encrypted size and refuses before starting, with the real number.

NOT OURS TO HOLD

Cryptomator format

The format is Cryptomator's, rebuilt from its public specification, and it works both ways — tested. Vaults made here open in Cryptomator on Android, iOS, Mac and Linux, with nothing to convert. Vaults you already have open here too. If ExplorerFocus went away tomorrow, the files would not.

Protects against

  • Anyone who copies the folder or the disk — cloud sync, a lost USB stick, a backup in someone else's hands
  • Anyone who steals the computer while it is switched off
  • Anyone with read access to the disk, without the password

Does not protect against

  • Malware running as you with the vault open — it reads decrypted files, like any other program
  • Keyloggers, or anyone sitting at your unlocked machine with the vault open
  • Copies of a file that already existed in the clear before it went in
  • Someone who writes to the disk with the vault closed: they cannot alter your content — the authentication catches that — but they can delete files

Why that second column exists: promising more security than it has is the worst thing a feature like this can do. Every product in this category could publish that list. Almost none of them do.

A side effect worth knowing: every encrypted folder lives at the same shallow depth on disk, so a folder twenty levels deep is still a four-part path. Paths that Windows Explorer refuses to open work inside a vault.

PREMIUM — creating vaults. Opening them is free, including vaults made elsewhere.

Built with serious parts.

Each dependency was chosen for maturity, size, or the absence of reasonable alternatives. No framework-of-the-day.

The complete list travels inside the program, with every author and the full licence texts — under About → Third-party licences.

.NET

net10.0-windows

Classic WPF, no WinUI or MAUI. Compatible with Windows 10 and 11.

MVVM

CommunityToolkit.Mvvm

ObservableObject, ObservableProperty, RelayCommand — generated by source generators.

CRYPTO

Bouncy Castle

scrypt, AES-SIV and AES key wrapping, from Bouncy Castle (MIT) — public, and in wide use for over twenty years.

LETTER

Dokany · DokanNet

Dokany (LGPL v3) is not shipped: you install it, and the explorer uses it only if it finds it. The .NET bridge, DokanNet (MIT), does travel inside the executable.

FORMAT

Cryptomator v8 · BIP-39

The vault format is Cryptomator's, rebuilt from its public specification. The recovery key uses the BIP-39 word list (MIT).

PREVIEW

AvalonEdit · Markdig · WebView2

Syntax highlight, markdown renderer, and embedded Edge engine for PDF.

UTIL

Microsoft.VisualBasic.FileIO

For sending to the Recycle Bin — the only honest way, and it works.

REMOTE

SSH.NET · FluentFTP

SFTP through SSH.NET; FTP and FTPS through FluentFTP. Mature, and boring in the good way.

NO SDK

HttpClient

WebDAV, Dropbox and OneDrive are written by hand against their HTTP APIs. No vendor SDK to age badly.

CAPTURE

NAudio · Concentus · NTwain

Microphone and system sound through NAudio and WASAPI; WhatsApp voice notes (Opus) through Concentus; the scanner through NTwain, the TWAIN standard.

ARCHIVES

SharpCompress

ZIP, RAR, 7z and TAR read in place, so an archive opens like a folder.

PDF

PDFsharp · PdfPig

Merging, splitting and organizing pages through PDFsharp (MIT); reading the text, the X-ray and the translation through PdfPig (Apache 2.0). Licences are checked at every new version, not just every new package.

LISTEN AND WRITE

Whisper · llama.cpp · ONNX Runtime

The ear is Whisper (OpenAI), through Whisper.net and whisper.cpp. The translator is LMT-60 (NiuTrans) on llama.cpp, or the lighter M2M100 (Meta) on ONNX Runtime. All MIT, except LMT-60, Apache 2.0. The models are not inside the program: they come once, only with permission.

WINDOWS

Media Foundation · WIC · OCR

Video, images, reading text and finding faces use what Windows already ships. No extra library to age badly.

PLACES

GeoNames

Near… uses the names and coordinates of places from GeoNames, under the CC BY 4.0 licence, and works without internet. Changed: only places with more than 1000 inhabitants or seats of a municipality or region, without districts or historical places, and only the names in the app's languages.
