Some time ago I saved a .jpg file I found on the Internet to my desktop, giving it a name that ended with a period. Having done that, I found that the file on my desktop was now an unusable blank, I assume because of confusion caused by that period, so I deleted it and saved the .jpg again, under a different name, and then moved it to another folder on another partition. I didn't give the incident another thought until weeks later, when the same blank file I had deleted reappeared on my desktop, from which I have found it impossible to delete, rename or move. Not, I am told, because I can't modify the file, but because it supposedly doesn't exist. It has a size of 0 bytes, so there's no practical reason to mind it, but it irritates me to have it cluttering up the desktop I so carefully optimized. I'm this close to formatting C: and reinstalling Windows and everything else I had there over this little bug, but I'm hoping for a less drastic solution.
