I had been struggling with a folder for hours and hours. I don't have time to reboot my system in safe mode or make some monumental changes every single time I am working and want to rename a file or a folder. This little feature in XP just sucked. But, when I got the Unlocker program version 1.8.5 IT WORKED LIKE A DREAM! Right after download and install, I right clicked on the folder, choose the unlocker and was able to rename the folder in seconds. These guys only ask for a donation. I can't give much but I will be donating for sure!
