About this app
Open a USB flash drive on your phone, move files across, and get your storage back. No sign-up, no subscription.
Plug a USB drive into your phone with an OTG adapter and USB File Manager finds it on its own. Browse it, copy files either way, and see exactly what is taking up room. If your drive is not showing up, the app tells you why instead of leaving you guessing.
WHY ISN'T MY USB DRIVE WORKING?
Most apps in this category show one unhelpful "no device found". This one checks what is actually happening and gives you the fix:
• Your phone has no USB host hardware, and no adapter can change that
• Nothing is plugged in
• Your port is busy charging, so a drive cannot connect at the same time
• Something is attached, but it is not storage
• A drive is attached but Android cannot read its format
• The drive is ready and waiting for one tap
Five of those six have a different answer. You get the right one.
BROWSE WITH REAL PREVIEWS
Photos and videos show actual thumbnails, not grey icons, straight off the drive. Switch between list and grid. Sort by name, date, size or type.
SEARCH THE WHOLE DRIVE
Look through every folder at once, not just the one you are standing in. Results appear as they are found and each one shows the exact folder it lives in.
MOVE FILES WITHOUT LOSING ANY
• Select as many files and folders as you like
• Copy or move between your phone and the drive in either direction
• Live progress with real transfer speed and time remaining
• Leave the app and the transfer keeps running
• If a name already exists, you are asked what to do instead of the app silently overwriting your file
• Every transfer is logged, so you can see what moved and where it went
FREE UP SPACE
• Exact duplicates, matched by comparing the full file, not just its size or name, so nothing is deleted by mistake
• Large files, ranked biggest first
• Files you have not touched in months
• Nothing is ever pre-ticked. You choose what goes, and confirm before it does
ZIP FILES
Compress anything to a ZIP archive, or extract one straight into the folder you are in. Folder structure is preserved both ways.
STORAGE ANALYSIS
See a full breakdown of any drive or folder by file type, with the biggest files listed, so you know what is actually filling it up.
BUILT TO RESPECT YOUR PHONE
• No account, no sign-up, no subscription
• Nothing is uploaded. Your files never leave your device
• Works completely offline
• No permissions required to use USB drives. Full phone storage access is optional, explained before it is asked for, and can be turned off any time
• Light and dark themes
WHAT YOU NEED
A USB OTG adapter, which is a small, inexpensive connector between your phone and the drive. Make sure it says data transfer, because charge-only adapters carry no data lines and look exactly like a dead drive. The app includes a short guide explaining this.
Android reads FAT32 and exFAT drives. Drives formatted as NTFS usually will not mount, and the app tells you when that is the problem.
WORKS WITH
USB flash drives, pendrives, SD card readers, portable hard drives, and your phone's own storage and SD card.
