A free app for Android, by New Year App 2019.

OTG USB Driver is the most powerful, easiest, and most modern tool for accessing and managing your USB flash drives and SD cards on your Android device. With this application, you can easily manage all the files and folders on your device, regardless of whether they are stored on your internal flash drive or an SD card.

This app is designed to work with all USB flash drives and SD cards that use the USB on-the-go (OTG) specification. If your device does not have an OTG port, or if you are not using an OTG-compatible USB flash drive, you will not be able to use this app.

The app will detect all the connected USB flash drives and SD cards, and will let you browse the content of your device. You can easily create new folders, rename folders, and move files between drives.
