Look at the message again: is it C:\RECYCLER or C:/RECYCLERS
The 2nd is not even a valid name so that is bogus if it says that. You've got other problems, then.
If it really is C:\RECYCLER then it IS a hidden / system file. Check your views settings again for your folders.
While you are showing hidden / system files / folders check if you can see other hidden files: the cache file (swap file) and/or LOCAL SETTINGS folder under your profile or others' profiles under C:\Documents and Settings\
