Chapter 1: Accidentally Deleted Files from a Flash Drive?

You may have removed some files from your disk, thinking they would go to the Recycle Bin or Trash. But the truth is those items will bypass the bin. When you delete something from an external drive, it's similar to emptying Recycle Bin or Trash on your computer. But there is still a way to retrieve them.

How to recover: the best way is to use a USB data recovery program (as we introduce below). Beware that such software only recovers deleted files that are not overwritten yet, meaning you'd better stop using your flash drive the moment you hit the delete operation.

Chapter 2: Formatted USB Flash Drive By Mistake?

Sometimes you need to release more disk space, so you just "quick format" the drive without thinking much about the data stored inside. The operation is irreversible meaning there is no such "unformat" function. Fortunately, it's still quite possible to rescue the data. 

How to recover: once again, by using USB data recovery software. A quick format on a flash drive won't erase the data inside immediately, the data will retain intact there for a while depending on how large its volume is and how aggressive you generate additional data. Similar to accidental deletion, these formatted files are recoverable only if they are not fully written over.
