All I can find is a delete items from Library 1 by 1 methods on the FAQ page and you have to be a bit nimble fingered to do that

BUT... Have you got Crapcleaner?(
www.ccleaner.com ) this will clear them Hopefully with No effort
Download and Install this
Then before you do anything untick the Cookies and History boxes in the top section also make sure the Advanced Section Box is unticked also<< IN
Left Pane
Next click the cleaner icon then the Analyze button
Will take a few minutes then a list is shown in the pane can stop it if there is a file you want? though it is quite kind on text files and custom folders
If you are satisfied then click the Run cLeaner button
And a minute or 2 later a message abears telling how much was removed ...Ok to close the program now
Now what do you find?
If its still there return to ccleaner and this time click on the Blue "Issues " icon then the "Scan for issues" th button this will clear a lot of the Usless item out of the Registry Left over after changes or deletions...And It is very good /Safe and the Fixed selected issues button when press showa a list of what the Program has found and offer you the chioce to keep them if you wish or delete some...I delete them all. I trust this program have had no problems afterwards
I run this before a defrag and It does speed up the defrag and "slow" computers afterwards...Great if you have dial-up
Has several other party tricks too that are helpful shortcuts without going into Windows
