I am attempting to transfer files. I have opened Explorer twice, once on the left and once on the right and want to transfer Folders in the left hand Explorer to a new location. This should be easy. Having done the same for years, in previous version of Windows, I (silly me) expected it to work the same in Windows 7 Explorer. Sometimes when I Cut a folder from one location and Paste it into a new (quite different) folder in another, I get the following : "Folder in Use" "The action can't be completed because the folder or a file in it is open in another program. Close the folder or file and try again." This is complete twaddle, nothing is open in another program. The only activity is two instances of Explorer. No open files anywhere. It doesn't happen all the time, and goes away when I reboot, which is the only time I can then Cut&Paste the Folder to where it is supposed to go. This never happened in XP (I avoided Vista). Can anyone throw some light on why this happens? Grrr. Grenou.
