Simple browser cache cleaner for Windows. PolarityFlow · Adrian Zingg
Project home: G:\POLARITYFLOW\DEVELOPMENT\PROJECTS\2026\CacheFlow
- Scans the system for installed browsers: Chrome, Edge, Brave, Vivaldi, Chromium, Opera, Opera GX, Firefox, LibreWolf, Waterfox, DuckDuckGo (Microsoft Store version).
- Shows per browser: installed version, profile count, current cache size (✓ Clean badge when under 5 MB), last-cleared date and whether the browser is currently running.
- Checks for newer browser versions (Chrome, Edge, Brave, Firefox, Opera, Opera GX — official release feeds; needs internet, fails silently offline) and shows "↑ vX available" / "✓ up to date" per browser. Results are cached per session.
- A progress bar shows scan/clear activity; buttons are locked while working.
- Clear selected deletes cache folders only (HTTP cache, code cache, GPU/shader caches, service-worker caches). Browsers rebuild these automatically.
Passwords, visited sites (history), cookies/logins and autofill data are kept by default. Uncheck a box to wipe that data too — the tool asks for confirmation first.
Notes:
- Firefox-family history is never touched (it lives in
places.sqlitetogether with bookmarks). - A running browser locks some files; CacheFlow skips locked files and tells you. Close the browser first for a full clean. (Edge often runs in the background on Windows 11.)
Double-click CacheFlow.exe — that's it.
No installation, no admin rights, no dependencies — fully portable. The exe is a
native C# WPF application targeting .NET Framework 4.x, which is part of Windows.
Last-cleared dates are stored in cacheflow-state.json next to the exe.
Windows SmartScreen note for downloaded copies: the exe is not code-signed, so
SmartScreen may show "Windows protected your PC" — click More info → Run anyway,
or right-click the ZIP → Properties → Unblock before extracting. The included
C# source (src\Program.cs) is the transparency guarantee: it is the exact code
inside the exe, and anyone can rebuild it with build.bat.
Run build.bat. It compiles src\Program.cs with the C# compiler that ships
with Windows (%WINDIR%\Microsoft.NET\Framework64\v4.0.30319\csc.exe) — no SDK,
no NuGet, no internet required. The app mark (assets\AppIcon_256.png) is
embedded as a resource and CacheFlow.ico becomes the exe icon.
(The original PowerShell implementation is kept in legacy_powershell\ for
reference; the C# version is the one that ships.)
The ♥ Donate button opens a dialog with PayPal and crypto options. The links and
addresses are configured in the Donate array near the top of src\Program.cs.
Entries set to "" are hidden. Rebuild after changing them.
