I mean if your trying to delete like important files I dont think they should be deleted but that is My opinion. But if you do delete them then u could always got to the recycle bin in ur computer to get it back. I hope this helps !!
Most of the time important files shouldn't be deleted. Sometimes a file can be used as evidence in the court of law. If the file is work related it shouldn't be deleted because it may be important for further research.
