9G Files

A powerful file manager that gives you complete control over everything on your phone — without the clutter, limits, or compromises of stock apps.

📁 Manage Your Files — the Way You Want

Everything you'd expect, and a lot you probably haven't seen in a file manager before.

- Copy, move, delete, and rename files and folders, including across SD cards and USB drives - Select multiple files at once and act on all of them — move, share, compress, delete — in one tap - Batch rename a whole folder of files at once: add a prefix, a number counter, or use a pattern to rename dozens of files in seconds - Drag and drop files between the two side-by-side panels - Long-press any file for a quick peek — see a photo thumbnail, a text excerpt, or media info without opening it - Recycle bin catches deleted files so you can restore them any time within 30 days - File shredder permanently wipes files with a 3-pass overwrite — nothing can be recovered afterwards - Split large files into smaller parts for easy transfer, then reassemble them when you're ready - Edit a file's date — change when it was last modified, useful for organising photos or documents - Pin any folder to your home screen as a shortcut for instant access

🧭 Navigate Without Getting Lost

- Two panels side by side — open two folders at once and drag files between them - Tap any part of the path bar to jump straight to that folder - Back and forward buttons for folder navigation, separate from your phone's system back gesture - Each folder remembers its own sort order — sort your Music folder by name and your Downloads folder by date - Recently visited folders appear on the home screen so your most-used locations are always one tap away - Bookmarks let you save any path as a permanent favourite - File tags — attach coloured labels to files for your own custom grouping and filtering - Three view densities: compact, normal, or comfortable - USB drives and SD cards are detected the moment you plug them in, no refresh needed

🔍 Find Anything, Fast

- Search inside files — not just file names, but the actual text content of documents, code files, and more - Regex search — full pattern matching to find files by name - Filter by file type — show only images, videos, audio, documents, archives, APKs, or code files - Filter by size — find tiny files, large files, or anything in between - Filter by date — narrow results to files modified or created within a specific date range - Search history — recent searches appear as suggestions - Category tiles on the home screen — tap Images, Videos, Audio, or Documents to instantly browse every file of that type

👁 Open and Edit Almost Anything

🔐 Keep Your Files Safe and Private

┌─────────────────────────────────────────────────────────┐ │ 9G Files Encryption │ ├──────────────────────────┬──────────────────────────────┤ │ Password encryption │ Device-key encryption │ │ (.9genc, format 9GEF) │ (.9genc, format 9GEK) │ │ │ │ │ PBKDF2-HMAC-SHA256 │ RSA-2048 OAEP/SHA-256 │ │ 120,000 iterations │ wraps an AES-256-GCM │ │ AES-256-GCM payload │ session key │ │ 16-byte salt + 12b IV │ │ │ 96-bit GCM auth tag │ Encrypt on one device, │ │ │ only readable on another │ └──────────────────────────┴──────────────────────────────┘

- Encrypt any file with AES-256-GCM — the same standard used by banks. Set a password and the file is unreadable to anyone without it - Device-to-device encryption — use the Publisher Tool to encrypt files with the recipient's RSA-2048 public key; only their specific device can decrypt them. No shared passwords, no key exchange risk - Secure Vault — a biometric-locked hidden folder; files moved into the vault are invisible to every other app - App lock — require fingerprint or PIN before 9G Files even opens - Password-protected ZIP archives — AES-256 encrypted archives - Checksum verifier — confirm a downloaded file hasn't been corrupted or tampered with: MD5, SHA-1, or SHA-256 - File shredder — 3-pass overwrite that makes deleted files forensically unrecoverable - File permissions viewer — see read/write/execute permissions in rwxr-xr-x format
