I had to get in the way-back machine today.
We have a windows 2003 server (I know...) where we are moving some files around.
One of the folders would not allow us to delete it, giving the good old error:
"Cannot Delete Folder: Cannot Read From Source File Or Disk"
We used to see this sort of thing all the time back "in the day" but I figured I should put this down for future generations of computer archaeologists. (and perhaps anyone who gets burned by misbehaving file names)
get a command prompt, and navigate to the folder that holds the "undeletable" folder/file
issue the following command:
this will show you the contents of the folder, including the 8.03 dos name of the file (it is shorter, and generally has a ~ in the name)
then simply issue the command DEL with the 8.03 filename, and viola, it should be gone.
