No problem Steve. Most people don't even know about those files. I do a lot of messing with my folders and deleting old files and such. And I have found out the hard way a couple of times that I deleted one that I shouldn't have in some folder, but I always send them to the trash bin and I can go there and tell it to put the file back. I normally leave any that I am not sure of in the bin for a few days before I get rid of them completely. Like old log files and stuff that hasn't been used in months. There are always left over files from programs and such.
