USB OTG Flash Drive Manager

Your phone says storage full, and the photos filling it are the ones you actually want to keep. USB OTG Flash Drive Manager moves them straight onto a USB flash drive or pen drive. No computer, no cable to a laptop, no cloud subscription.

Plug the drive into an OTG adapter and the app finds it for you.


MOVE FILES BOTH WAYS

• Browse a USB flash drive on Android like any other folder
• Copy or move photos, videos, music, documents and APKs between phone and drive
• Back up your phone to USB, and restore from USB back to your phone
• Live progress with transfer speed and time remaining, and cancel whenever you want
• Photo and video thumbnails, so you can see what you are moving instead of guessing from a file name


FREE UP SPACE THAT IS ALREADY WASTED

• Find duplicate files by content, not by name, so "IMG_2043.jpg" and "IMG_2043 (1).jpg" are caught
• Delete duplicate photos and videos, and see exactly how much space you get back
• Clean out empty folders left behind by apps you uninstalled
• Move the big files to your drive, then delete the originals in the same pass


WORKS WITH REAL DRIVES

Full read and write on FAT32 and exFAT. Reads NTFS drives that Android normally refuses to open, so a drive formatted on a Windows PC still opens on your phone. When a drive is read-only the app explains why and how to fix it, instead of silently failing.

Works with USB flash drives, pen drives, thumb drives, card readers and USB hard drives through a standard OTG adapter.


NOT SURE YOUR PHONE SUPPORTS OTG?

Open USB OTG Check. One screen tells you whether your phone's hardware supports USB On-The-Go at all, before you spend money on an adapter. USB Info then shows your drive's real capacity, free space, file system and connection speed.


ABOUT PERMISSIONS

Managing files on both your phone and your USB drive requires Android's All Files Access permission. It is used only to read and write the files you pick, inside the app. Nothing is uploaded anywhere. Every transfer happens locally, between your phone and your drive.


WHO IT IS FOR

• Anyone whose phone storage is full and who does not want to rent cloud space
• Photographers and videographers offloading a shoot while still out
• Anyone moving files between phone and laptop without hunting for a cable
• People who keep documents on a pen drive and want to open them on their phone
