The deleted things on the USB flash drive can be retrieved, but only if the data is not overwritten. When a file is stored in the U disk, the file record is also stored separately from the file data. When deleting a file, the file record is deleted, and the file data is still saved in the U disk, but it is out of sight. Before the deleted file is overwritten by the newly stored data, the file can be recovered through data recovery. Therefore, after deleting a file, you must avoid writing to prevent the file from being overwritten. The following is the recovery process: 1. Insert the U disk into the USB port of the computer, the computer can detect the U disk, and the "mobile disk" representing the U disk can be seen in "My Computer". 2. Install and run the data recovery wizard software in the computer, then choose to recover the deleted files, then choose the USB flash drive and start scanning the files. 3. The scanning process software will list the found files, and then you can preview and judge the files. After finding out the files that need to be restored, check the files (check the small box in front of the files), and then click the "Next" button to copy the files to your computer. Note: Before the file is restored, the data cannot be saved to the U disk, so in this step, the file should be saved to the computer first.
