To learn more about how to recover files, you should start by looking whether the files you want to recover are still available in your Recycle Bin/Trash. You can also go through your cloud storage and other backup storage if you have any. In case the files have been deleted forever, minimize the usage of the storage device in order not to overwrite the deleted files. There are many software available on the internet that can be used to scan the drive for the files.
