OTG Reader – Browse USB Drives on Your Android Device

OTG Reader is a free Android app developed by SweatersApp, designed to help you browse USB flash drives and card readers from your phone or tablet. All you need to do is connect the flash drive to an OTG (On-the-go) cable, then introduce the small USB connection of your device, and open the app. You’ll be able to see all files on the USB drive and open them with your favorite app viewers or editors. The app currently supports the FAT32 disk format of flash drives.

With OTG Reader, you can automatically start the app when you connect the device, and mount and unmount the drive with just one click. The app also offers full NTFS support, and exFAT support, and notifies you when drives are mounted. Additionally, it loads modules needed automatically, and you have the option to alter utf-8 mode. The app also automatically opens the mounted drive and triggers the media scanner on the mount.

Please note that the fatless version limits line size to 30 MB. If you need to open a file larger than 30 MB, please consider using a USB OTG Reader.
