Deleting That Stubborn File?
Hello Folks:
I too, had a file (MPEG), with a very long name, that Win XP would not allow me to remove. After folllowing all of the DOS-based tricks and using a bunch of third-party utilities, I found a small, free/commercial utility that finally did the trick: "JRTS Delete FXP Files".
You can Google for their website if you're inclined. I downloaded their 'free' version, which even though very limited, allowed me to finally get rid of the offending file (without rebooting). It sure saved me a boat load of additional headaches and time-consumption. Check it out. It may be just what the doctor ordered.
