Amaze File Manager is another open-source option for browsing storage, and Fossify File Manager sits in the same camp while keeping its focus narrow. It is a free file explorer from the developer Fossify, listed in the file managers category with no ads. Version 1.6.3 is 9.6 MB and was last updated on October 27, 2026.
Fossify and the GPL-3.0 source on GitHub
The app comes from Fossify, which runs a site at fossify.org and publishes its code under the FossifyOrg account on GitHub. The file manager is licensed GPL-3.0-only, and the source repository is public. The first release was on January 15, 2024.
The package ID is org.fossify.filemanager. The app has no in-app purchases and no ads. It also points to community pages on Reddit and Telegram.
Home folder, locks and the storage analysis tool
Day-to-day handling covers compression, file transfer, search and sorting. You can set a custom home folder and add favorite shortcuts, so the folders you use most are one tap away. Desktop shortcuts for files and folders are also described.
Privacy tools are a notable part of the list. Hidden items or the whole app can be locked with a password, pattern or fingerprint. The app needs no internet access, so files stay on the device.
For space problems, a built-in storage analysis tool helps find large files, and compression can shrink files and folders. A light editor handles reading and editing documents with zoom gestures, and printing is mentioned too. Colors, themes and icons can be changed, and root files, SD cards and USB devices are covered.
Android 8.0 minimum and a small 9.6 MB install
Fossify File Manager needs Android 8.0 or newer. At 9.6 MB it is light on storage, which suits an app meant to help free up space.
Alternatives include Amaze File Manager, Files by Google, Google Drive, Microsoft OneDrive, APK Explorer & Editor and FilePipe. Note that Drive and OneDrive are cloud services, while this app works on local storage.
