[Tutorial]: Free Ways to Recover from Deleted Files from USB
Why we can recover from deleted files from USB?
To know why you can recover deleted files from USB flash drive, you should first understand the storage principle of USB flash drive.
When a file is written to the USB flash drive, the operating system will check the file allocation table to find the storage space, then store the file in the corresponding sector on the USB flash drive and record its location in the file allocation table. So the file is stored in two locations on the USB. That is, it is stored in the file allocation table and stored in the corresponding sector.
If the file is deleted, the operating system deletes the file stored in the file allocation table, but not the file stored in the sector. Since the file allocation table deletes the file information, the operating system no longer knows where the file contents are stored and thinks the file is deleted. Therefore, disk sectors are marked as free and can store new files. However, these deleted files are still saved on the USB stick and can be recovered. However, if the system stores new data in this area and occupy these sectors, the deleted files will be overwritten and cannot be recovered.

Why do people want to recover from deleted files from USB? Here are a few common reasons for USB file loss:
- Accidentally deleted files from a USB flash drive
