Enter Space Reclaimer. Space Reclaimer is a little utility that will clean most of your temporary files for you. It's quite simple to use. Just install the file onto your PDA and launch it. There will be a shortcut for you in your Programs folder.
Once launched you are presented with the option of telling Space Reclaimer where to search for junk. As you can see (picture above) it's very easy to uncheck the boxes next to the things you do not want to do.
One feature I really like is the ability for Space Reclaimer to shut down running programs. This can be very helpful as I often find myself going to the memory manager to try to shut down programs manually. The only issue you might have is if you're listening to mp3 files while you're running Space Reclaimer. It will try to shut down Windows Medial Player which will mean your music will stop playing. Other than that the shutting down of programs you're not currently using is a real plus.
After the program cleans out your Pocket PC it will give you a summary report of what was done. This lets you keep track of what files are deleted. You can also set how Space Recalimer starts with the Settings screen.
Most of us do not need all the temp files so I try to get rid of them. If you do need a specific Internet cookie then simply tell Space Reclaimer not to get rid of your cookies and it will leave them alone. At $5 this software is a real deal.
