1B Files: File Manager & FTP

1 Byte Systems

About this app

1B Files is a file manager and file explorer for Android by 1Byte Systems: all your storage at a glance, space cleanup, your servers and your PC, and an encrypted folder for private files. No ads, no analytics, no accounts.

EVERYTHING AT A GLANCE
• Home screen with internal storage, SD card and USB, plus Images, Audio, Videos, Documents, Downloads, Apps and New files
• Choose which shortcuts appear on the home screen and in what order
• Storage analysis to see which folders take up space
• Quick search on internal storage, SD card and USB, with filters by type, size and date

COPY AND MOVE WITHOUT LOSING DATA
• Each copied file is written to disk and checked before the original is deleted; if something fails, the original stays intact
• Long operations run in the background with a notification, can be cancelled and wait in a queue
• Name conflicts: replace, skip, keep both or merge folders
• Trash keeps deleted files for 30 days (adjustable), with Undo

FREE UP SPACE
• Junk, large files, old screenshots and old downloads
• Duplicate files, always keeping at least one copy
• APK installers of apps you already have
• App cache size (with usage access)

FILE TOOLS
• List or grid, favorites, recent and hidden files
• ZIP, 7z, RAR and TAR: view the contents and extract, also with a password; create ZIP files with AES-256
• Text editor with find and replace
• Batch rename with patterns, numbering and a preview
• Checksums (MD5, SHA-1, SHA-256)
• Viewer for photos, videos, music with a playlist, text, code and PDF
• Apps: see installed apps and their size, uninstall them, extract the APK and install APK files
• Dual pane on tablets and unfolded foldables, with drag and drop between panes. Folding keeps your folder, selection and scroll position

REMOTE SERVERS AND YOUR PC
• SFTP (password or SSH key, fingerprint check), FTP/FTPS, SMB (Windows and NAS shares) and WebDAV (Nextcloud)
• Browse, copy, move, rename, create folders and delete on the server, and copy between the server and your phone
• Play videos and music and open photos from the server without downloading them first
• Access from PC: open the address in your computer's browser and enter the PIN shown on your phone to view, download and upload files. Wi-Fi or hotspot only; it turns off by itself when not in use
• Cloud folders of other installed apps through the Android file picker

ENCRYPTED SAFE FOLDER
Files in the safe folder are encrypted with a key kept in Android's secure hardware and only open after your fingerprint or PIN. The folder locks again after a few minutes and is hidden from recent apps. Its contents stay on this phone and are erased if you uninstall the app.

FOR EVERYONE
• Works with TalkBack
• Light and dark theme, for phones, tablets and foldables
• 21 languages

PRIVACY
No ads, no analytics, no accounts. 1B Files asks for "All files access" to manage your files; they stay on your device and only go where you send them.
