Everything a file manager should do

Browse every folder

Internal storage, SD cards, and USB drives, in list, grid, or details, with tabs for moving files between folders.

Find anything

Search names, paths, and extensions across all your storage, with filters for type, size, and date.

Free up space

See the largest files, exact duplicates verified by checksum, and empty folders. Nothing is removed until you review it.

Safe file operations

Copy, move, compress, and extract with pause, resume, and cancel. Conflicts always ask, and the trash has undo.

Share with your computer

Open your phone's files in a browser over Wi-Fi. Off until you turn it on, local network only, and every computer needs your approval.

Private by design

No account, no ads, no analytics. Your files never leave your phone unless you share them.
