Lumen - File manager

Lumen Files is a file manager that respects your privacy. No account, no ads, no tracking: your files stay on your phone unless you choose to share them.

Your storage at a glance

See free space, recent files, your common folders, and every file type on one screen. Pin the folders you use most, and add widgets and shortcuts to your home screen.

Browse every folder, fast

• Internal storage, SD cards, USB drives, and folders from other apps

• List, compact, details, and grid layouts, remembered per folder

• Tabs and a second pane, so two folders stay open while you move files

• Thumbnails for photos, videos, PDFs, and apps

• Browse ZIP archives like folders

Find anything in seconds

A private index on your phone searches by name, path, or extension across all your storage, with filters for type, size, and date.

Free up space, safely

• Find the largest files, folders, and old downloads

• Exact duplicates, verified by checksum

• Similar and blurry photos, old screenshots, and chat media

• Empty folders and leftover files

Lumen only suggests: you review everything, and nothing is removed until you say so.

Safe file operations

• Copy, move, rename, share, compress to ZIP, and extract archives, including password-protected ones

• Never overwrites by surprise: choose replace, skip, or keep both

• Pause, resume, or cancel long operations

• A trash that works with Android's own, with undo

Send files between your devices

Pair your phones and tablets that have Lumen, then send files, folders, links, and text over Wi-Fi, like a chat. Transfers resume when a device comes back, and you choose what each paired device may see.

Share with any computer over Wi-Fi

Open your phone's files in a browser on your computer: download, upload, and organize them, or connect them as a network drive. Sharing is off until you turn it on, stays on your local network, and asks you to approve each browser. To give someone files without Lumen, show a one-time QR link.

Preview without leaving the app

View photos, play videos and music, and read PDFs, office documents, spreadsheets, ebooks, emails, text, and code right inside Lumen.

Private by design

Lumen Files has no analytics and no advertising, and it doesn't collect your data. Files you send go directly between your devices, never through a server. All files access is used only to manage your files, and Android still keeps other apps' private data protected.
