First of all, did you check your Recycle Bin?
If the files are no longer in there, you will need a tool to recover them. Fortunately for you, Windows doesn't actually delete files, it just removes them from its "table of contents". So if the files have not been overwritten with other data, you should be able to recover them. Card Data Recovery is nice program that can help you get back deleted file due to mistakenly delete, virus attack, format, etc.

Accidentally deleted files into recycle bin? Go to Recycle Bin and click "Restore".
Can't find it there? Don't worry! You can get them back!
Deleting won't make the data on a computer erase permanently(Even permanently deleted with "Delete + Shift" or emptied recycle bin).Those deleted files are still stored on your PC, they're just invisible or inaccessible. You can recover them with data recovery software. But once the deleted files were overwritten by new data,they are gone for good.
I used to recover deleted files from my laptop with Tenorshare Data Recovery.
Anyway,you can download it and scan your PC for free to preview whether you can recover your deleted files.
