If you're looking for a complete cleaning, reorqanising and all round general cleansing solution for your Windows Mobile device, then SKTools comes packed with a bunch of tools to make your life easier.

This is a genuinely powerful maintenance toolkit with so many tools included it's hard to know where to start. All of them combine to ensure that your registry is clean, your hard drive spic and span and that your RAM is completely flushed clean. Tools at your disposal include those to clear your temporary and cache folders such as IE contents, IE history, Mail attachments, Terminal Server client cache, Opera cache, NetFront cache and custom folders. In addition the program finds and deletes temporary, empty and obsolete files, malicious or corrupted registry keys and values, faulty shortcuts and other files that are deemed to be taking up valuable space on your portable device but are not needed anymore. It also of course empties recycle bins and deletes temporary files. The FreeUP RAM tool is probably one of the nicest feature of this toolkit allowing you to free up to 50K-2M of RAM. It can be set to kick in whenever your RAM reaches below a certain point and close tasks that are hogging your RAM. Note however that it can sometimes struggle to deal with excessive RAM usage and end up slowing down your system more than speeding it up.

This is a handy set of tools for Windows mobile devices that does an efficient job although apart from the RAM cleaner, doesn't perform anything you wouldn't normally expect from such a package.
