Filet

Most Android file managers treat storage as one place: the internal volume, listed. Filet has one storage interface underneath everything, and every backend is a plugin behind it. A zip is a folder. An APK is a folder, and classes.dex inside it is a browsable tree of smali. A WebDAV share is a folder. A feature written once works in all of them.

Features

Browsing

- Two panes, labelled A and B, each with its own history and selection. - Drag between panes: same volume moves, a different volume copies, with a preview under your finger. - Six view densities on one slider, from compact list to large grid. - Thumbnails for images, video frames, album art, and APK icons, cached on content so a rename does not re-decode anything. - Path bar accepts bare paths like /sdcard/Download. - Per-extension default openers, with remembered app choices.

Search

- Whole-device search answers in milliseconds, including inside APKs. - Two-stage: SQL narrows the index, then a scorer reranks in memory. - Fuzzy matching with word-boundary and camelCase bonuses, plus typo tolerance. - Frecency so what you open often and recently floats up. - Query language: type:, size:, modified:, in:, from:, pkg:, class:, perm:, inzip:, dup:, with AND, OR, NOT, and grouping. - Four scopes as chips: this folder, subfolders, whole device, provenance. - Every hit re-verified against the filesystem before display.

Archives and APKs

- Browse into an archive as a folder. Zip and everything zip-shaped, tar through gzip, bzip2 or xz, 7z, RAR and RAR5 including solid archives, and single compressed files. - Create archives in zip, tar, tar.gz, tar.bz2, tar.xz, or 7z. - Zip encryption with AES-256, AES-128, or the legacy ZipCrypto (offered and labelled weak). - Split archives in both directions: zip volumes or a numbered .001 byte split. - Extraction preview: destination shown as it will be, overwrite warnings, size estimate, and any entries trying to write outside the folder. - Automatic wrap and unwrap based on archive structure. - Edit a file inside an archive. Zip and plain tar re-compress only what changed. - Search inside archives. - RAR reading supported; RAR creation is not, due to licensing. - 7z with password is not supported, also due to licensing. - classes.dex opens as a tree of editable smali. - APK inspection: signature schemes, signer, SDK levels, native ABIs, protection status. - Edit the binary manifest without aapt2. - Rebuild and re-sign, reading minSdk from the APK.

Scripting

- Lua bound to the storage layer, so scripts work inside archives and on network shares. - Permission header declared per script and approved before running. - No io, no os.execute, no network. - Seven worked examples ship with the app.

Network sharing

- Any browser can open it. Nothing installed on the other machine. - Every reachable address listed and labelled by connection type. - Paths never enter a URL: /f/<token> makes traversal unrepresentable. - Optional PIN with QR code. - Live session list, revocable, non-expiring by default. - Folders open in the browser or download as a streamed zip. - Zero-copy streaming: sharing a large file costs no extra space.

Shortcuts and surfaces

- Home-screen shortcuts that survive a move by storing the file's index ID rather than its path. - Shortcuts to scripts and app actions, not just files. - Folder widget. - Crash reports shown on screen and kept locally, never uploaded.

Requirements

- Android 8.0 (API 26) or newer - Optional all-files access for whole-device browsing; Filet works without it but only shows folders you pick by hand - Optional foreground service for full index and active share

Permissions

- All-files access to browse the shared volume. - Foreground service (data sync) for indexing and sharing. - Internet and local network for sharing and network storage. No analytics, no crash reporting. - Install packages only when you tap Install on an APK or update.
