How to recover lost file/data

Step 1: Check the Recycle Bin / Trash

Step 2: Check for Backups 

Step 3: Check "Previous Versions

Step 4: Use Data Recovery Software (If No Backups & Not in Trash)

If the file isn't in the Recycle Bin/Trash and you don't have a backup, data recovery software is your next best option. It works by scanning the hard drive for fragments of deleted files that haven't yet been overwritten.

Step 5: Professional Data Recovery Services (Last Resort)

If none of the above methods work, especially if the drive has physical damage (clicking noises, not recognized by the computer), your only option is a professional data recovery service.
