Open every folder you need, keep your RAM

FileManager is a lightweight file manager for Windows, written in Rust on Zed's GPUI. Tabs, windows, expanded trees: it is built to scale with how much you have open, without growing into gigabytes of RAM.

Why another file manager

A file manager stays open all day, with a dozen tabs and a few windows. If every folder you open is indexed, cached and watched recursively, memory keeps climbing until it is measured in gigabytes. FileManager keeps for each open folder only what that folder needs, and caps everything shared.

Only what you see

Each tab lists its folder, without recursion. The tree view keeps only the folders you expanded.

One watcher, one folder

Change notifications for the listed folders only, never a recursive watcher on a whole tree.

Budgeted caches

Icons and thumbnails live in caches with a byte budget, shared by every tab and window: more folders open does not mean more cache.

Folder sizes only when you ask

Off by default. Turned on, they cover only the folder you are in, stop when you leave it, skip .git, node_modules, Intermediate, DerivedDataCache, and keep one number per folder.

A complete file manager

    Every view
    Details, tree, list, medium / large / extra large icons and Cover Flow. Switch with Ctrl + wheel.
    Tabs that travel
    Reorder them live, drag one out to a new window or onto another window, even of another instance.
    Explorer's menus
    A Windows 11 style context menu with every entry Explorer's menu has, and "Show more options" for the native one.
    The shell's file operations
    Copy, move, rename and delete through Windows, with its progress and conflict dialogs. Clipboard and drag and drop with Explorer, both ways.
    Recycle Bin inside
    Where each item came from and when, restore, delete for good, empty. Drop files on it to delete them.
    Dark, dimmed, light
    Three themes, five accents, English and Italian, all switchable at runtime.
