Steps and attempts to recover files:
Stop using the computer immediately to reduce the chance of overwriting deleted data.
Every new write operation on the disk increases the risk of permanently losing files.
Use a professional file recovery program:
There are many trusted tools to recover deleted files even if they are not in the recycle bin. The most popular are:
Recuva (free and easy to use)
EaseUS Data Recovery Wizard
Disk Drill
Important:
Do not install recovery software on the same drive you lost files from, as this might overwrite more data.
