File Management

FilDOS is a proper file manager before it is anything else. Every core operation works — and works fast — before any AI does.

​

Views

Switch between three layouts from the View menu:

• List — a virtualized table with resizable, reorderable columns.
• Grid — thumbnails at a few icon sizes, with cached previews.
• Gallery — a larger-preview layout for browsing images.

Your choice is remembered per folder. A deliberate change to sort order, view mode, or icon size becomes the new global default and the current folder’s remembered view — navigate away and back and the folder looks the way you left it.

​

Operations

FilDOS supports the full set of operations you’d expect from a native file manager: Copies and moves never overwrite — a collision gets a " copy" suffix instead.

​

Undo

Every mutation — copy, move, rename, duplicate — pushes an inverse operation onto the undo stack. ⌘ Z replays it.

​

Live updates

The file list subscribes to a non-recursive watch on the current directory. Changes made by other apps (Terminal, Finder, an installer) appear in under a second, debounced to avoid redundant reloads.

​

Drag and drop

• Internal (within FilDOS): move by default, hold ⌥ / Alt to copy.
• Drag out to Finder or Explorer: copies the file(s) to the drop target.
• Drag in from Finder or Explorer: moves or copies into the current directory.

​

Recents

FilDOS keeps a persistent Recents list that survives across sessions and updates automatically as files move. Open it from the sidebar. Like tags, recents are stored in SQLite and follow files through renames and moves — see Tags & Recents.
