One of the problems that plagues Windows users is the "locked file" problem. You know, the one that you want to rename or move, but you can’t because the file is in use…
If you’ve opened a document in Word, you can not rename the document on the disk drive until you close the copy in Word. You can save the copy that’s in Word, either with the same name or a different one, but that’s not always what you wanted to do.
I’m using Word as an example, but the same issue applies to any file that you open in a program. Until the program tells Windows that it has released the file, Windows protects you from making a dumb move.
Sometimes, though, Windows gets connfused. It won’t let you rename or move a file, but you’ve already closed the program that was accessing it. There doesn’t seem to be any reason that Windows should balk and refuse to make your change.
When that happens, sometimes, the easiest thing to do is to reboot. Then, once you’ve rebooted and are back into Windows again, you can make the change you wanted to make.
Other times, though, you may be able to solve the problem without rebootingn. That’s where a little freeware program I found came in very handy for me.
