What is the Command to Delete Temp files for all User profiles in a Local

I have a network computer that is used by more than 50 users per month, i have recently realized that the temp folder of each users as grown big and are consuming PC resources i want to delete all the Items in the TEMP folder of all the users that have logged on or used this computer, well doing it one by one is timing consuming and hard work too, because there is a profile for more than 100 users in.
??
I would like to know if there is a COMMAND that i can RUN to do this work for me? if so kindly advice. By the way the OS is Windows XP Professional. Also let me no if i can run it on the Network?

Thank u!
