whats a command line for deleting the contents of a folder but not the folder itself, I want to make a batch command that will clear my recent documents, prefetch, ect

Okay I figured out a command line... its....  

@echo off
del /q "path to folder I want to clear out*.*"
exit

and I saved it as a batch command, but it still leaves folders.... How do I fix that?

Also I made a little message that pops up when I use it but it will also say things like...

Could not find "path to folder"
then it will show my message, is there a command line that will tell it not to show that alert?
I'll attach two pictures so you can see what I mean. By the way, you'll need to zoom in on the
files to be able to see them because I had to put their quality way down because of the picture
upload restrictions.
