To recover files on a USB flash drive, download and install file recovery tools such as EaseUS for Windows or Jihosoft File Recovery for Mac, insert the USB flash drive to the computer, launch the recovery tool, and then follow the onscreen instructions to recover the lost files. The two data recovery tools can recover deleted files, formatted or damaged files, lost files or files lost due to unknown reasons.
For computers running on Windows, launch the EaseUS data recovery tool, and select the types of files you want to recover from the provided list. Click Next to proceed to the next step. Select the disk where you lost the data, and click Scan to find all lost files. Select Lost Disk Drives if you lost your partition, and then click Scan to proceed.
Preview the list of recovered files, select the ones you want to recover, and then click the Recover button. To avoid data overwriting, save the recovered files on another disk, and then exit the window.
For Mac computers, connect the USB flash driver to your computer, select the USB drive from the pop-up window, and then click Start Scan. Preview and select the files you want to recover, and then click the Recover button.
