A USB flash drive—also known as a pen drive, thumb drive, or memory stick—is a small, portable storage device that plugs into a computer's USB port and functions like a portable hard drive. These drives are widely used due to their compact size, portability, and compatibility with virtually any computer. They are primarily used to transfer data between devices.

Important Notes:

  1. If some files are not found by Deleted File Recovery, please click "Deep Scan" button to start the Deep Scan Recovery process, deep scan takes more time, but can find much more lost files.
  2. If the device you want to recover data from is encrypted with BitLocker Drive Encryption, try BitLocker Data Recovery.
  3. Do not save recovered files to the original device where data loss occurred, as this may overwrite the lost data.
  4. You can export or save the scan results for later use or future recovery.
