Question: how do I program my computer to periodically "dump" cache files? 

Answer: An easy way could be to write a windows batch file. Basically you need to know how to write a little DOS. You give it a destination folder and a keyword for deleting all files inside the folder. Or delete the whole folder and  then re-create it, but it might be risky. I forget how but it's easy to find instructions and writing the file. Then you can put this little file inside one of the windows folders for repeating tasks. Sorry to be so vague. It's absolutely possible and not that difficult, I just don't remember the exact details.\nAlso you can use freeware but beware of spyware.
