ERROR DELETING FILE OR FOLDER. Cannot Delete File: Cannot Deleter From Source or Disk What causes this. I was copying some files, my computer ended up bogging down in the process because I was very much doing to many things at once. Lately my computer has been less that cooperative, so I just turned it off manually, and restarted. Three random files showed up in the folder I was trying to copy stuff to. I can not delete them due to the aforementioned error. Right-click>Properties shows all three of the files to be 0 Bytes, and do not have an extension, but if I highlight the folder and let the yellow information box appear, it lists the files having last been modified 10/1/2029 and one file has grown to be 8 megs!!! What in the world is going on? Cliff notes. Random file appeared on my computer in a nonessential folder. The file was created in the year 2029 and personal attempts to delete the files were failures. What gives?
