If you’re on PC,. anything you delete, should be placed into the Recycle Bin,.. as long as you haven’t emptied that,.. then the files/folders will be there and can be restored from the recycle bin options.
If the recycle bin is empty,.
Then you’ve deleted the files,.. and trashed them.
While It’s possible to use a data recovery program to try to recover those files, you may need to know what you’re doing, as with all system tools they can be powerful, and in the wrong hands power tools can cause a lot of damage.
