Have you ever experienced loss of office files from a USB drive due to file download, USB format error, wrongly unplugging the USB drive? Whether you are using a Mac or a PC, similar file loss happens from time to time. Most people make regular backups of their computer, and if files on the computer are lost, we can use the backup to restore them. But what if your files are stored on a USB device? We rarely think of backing up USB devices, what should we do if we lose the files on the USB device?
If you are going through this, don't worry. There is still a good chance of recovering them by using some methods. First, we need to disconnect the USB drive from the computer to prevent other programs or viruses from continuing to write new data to it. And then restart your computer, do not run other application before connecting the USB drive to the computer. Then check the files on the USB drive and re-evaluate your missing files and folders.
1. Use Microsoft AutoRecover feature
If these documents were previously opened for editing with Microsoft Office and the AutoRecover option is turned on, you can use it to recover an earlier version of an Office file. The version of office file depends on when you saved it.
Open Microsoft 365 application or other version of Microsoft application you've used before, Go to File -> Info -> Under Manage Workbook or Manage Presentation, select the file labeled (when I closed without saving), In the bar at the top of the file, select Restore to overwrite any previously saved versions.
Or go to File -> Info -> Manage Document -> Recover Unsaved Workbooks in Excel, or Recover Unsaved Presentations in PowerPoint to recover unsaved files.
2. Recover with Fireebok Data Recovery
If using the Microsoft AutoRecover feature doesn't help you recover your lost Office files, there are still some data recovery tools you can use to search and recover from your USB drive's disk data. Because the file system only marks deleted or lost data blocks, deleted or lost data is still stored on the disk. Download and install Fireebok Data Recovery on your computer(PC or Mac).
Run Data Recovery application, and then select USB drive partition in the Data Recovery, and then select Deleted Recovery, Deep Recovery or Volume Recovery. If your files are deleted by other applications or by mistake, please select Deleted Recovery.
If you don't know what caused the loss, you can choose the Deleted Recovery, Deep Recovery or Volume Recovery, you can scan multiple times with different recovery modes. It will not affect the scan results because the entire scan process is read-only. After the scan is complete, you can preview and select the files you want to recover.
If your office files are lost due to a formatted or damaged USB drive, please choose the USB drive disk, not the partition, and then choose Lost Volume Recovery mode to find the lost or formatted partition, and then recover data from the scanned partition with Deep Recovery or Volume Recovery.
