In general, when you delete a file, windows just move it to the recycle bin, not really delete it, then the file can be restored easily from the recycle bin.
Further more, even if you delete the file from the recycle bin, or press the "SHIFT" key when you deleting it. The file was deleted by windows and can not be restored from the recycle bin. However, windows do not delete files permanently, in most cases, when you using a data recovery software such as Eassos Recovery, the file still can be recoverd.

There two options you can setup while you delete file permanently, "Fill file data with" and "Delete file entry".
"Fill file data with"
You can overwrite the file data with 00, FF, Random Data or specify a value to overwrite the file data. I recommand you simply choose the default value "00".
"Delete file entry"
I highly recommand you check this option, or some recovery software such as Eassos Recovery or Eassos PartitionGuru can detect the deleted file's name, though it' content can not be recovered forever.
