OTG checker & USB file manager: copy files from phone to USB flash drive

Copy files from phone to USB and from USB to phone. No PC, no laptop, no cloud and no extra USB driver needed. Phone storage full? Move your photos and videos straight onto a USB flash drive and free up space in minutes. PHONE TO USB FILE TRANSFER • Open a USB flash drive or pen drive on Android like any other folder • Copy or move photos, videos, music, documents and APKs from phone to USB and back • Back up your phone to a USB drive, and restore from USB back to your phone • Live progress with transfer speed and time left, cancel any time • Photo and video thumbnails, so you see what you are moving USB OTG CHECKER Not sure your phone supports OTG? Open the USB OTG Checker. One screen tells you if your phone's hardware supports USB On-The-Go, before you spend money on an OTG connector or OTG cable. USB Info then shows your drive's real capacity, free space, file system and connection speed. PEN DRIVE, FLASH DRIVE & USB DRIVE READER Full read and write on FAT32 and exFAT. Reads NTFS drives that Android normally refuses to open, so a pen drive formatted on a Windows PC still opens on your phone. When a USB drive is read-only, the app explains why and how to fix it instead of failing silently. Works with USB flash drives, pen drives, thumb drives, USB-C flash drives, SD card readers and USB hard drives through a standard OTG adapter (USB-C or micro USB). FREE UP SPACE • 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 how much space you get back • Clean empty folders left by apps you uninstalled • Move big files to your USB drive, then delete the originals in the same step HOW TO USE 1.
