If the files have not been permanently deleted then the files may be in the recycle bin.
Click on your recycle bin and see if the files are in there.
If not then you may not be able to recover them if they have been permanently deleted.
However if you're using Windows 10 you can use a recovery file option.
If you can’t locate a lost file from your backup, then you can use Windows File Recovery, which is a command line app available from the Microsoft Store.
Use this app to try to recover lost files that have been deleted from your local storage device (including internal drives, external drives, and USB devices) and can’t be restored from the Recycle Bin.
Recovery on cloud storage and network file shares is not supported.
