About OPFS Finder — Browse files like Finder
Browse browser's files
======================
A tiny Finder for the files every website quietly keeps inside your browser. Nothing new to learn — it just feels like home.
opfs-finder
===========
Browse your browser's hidden files — exactly like the Finder.
Every website quietly stores files inside your browser. Until now, you
needed DevTools to even see them. opfs-finder opens that hidden storage in a
window you already know how to use — icons, list, column, and gallery views,
drag & drop, rename, tag, search. Nothing new to learn. It just feels like
Finder.

Two ways to use it
------------------
As a Chrome extension
Click the toolbar button on any site. The Finder opens, showing that site's
files. Browse, preview, rename, move, and delete — wherever you are, the same
familiar window.
Install from the Chrome Web Store:

As an npm package
Add file management to your own app in one line. Your users get a real Finder
for their data — no need to build one yourself.
pnpm install opfs-finder
import finder from 'opfs-finder'
<button onClick={() => finder()}>
Manage my files
</button>
That's it. One import, one call, and your app has a Finder.
What you get
------------
- Four views — icons, list, column, and gallery, just like macOS.
- Full file actions — open, create, rename, duplicate, copy, move, delete.
- Drag & drop — move files around, or drop files in from your desktop.
- Tags, favorites, search — organize and find files the way you already do.
- Preview anything — even raw binary, shown as readable hex.
No setup. No config. It remembers how you like things and stays out of your
way.
