Windows Mobile has a built in file manager, but it’s slow and doesn’t give you all the features you’re used to in Explorer. Total Commander CE fills this gap. In addition to letting you view hidden and system files and having a search feature, there are also included plugins for FTP and registry. These allow you to move files around via FTP and to edit the registry on you Windows Mobile device. I’d recommend reducing the font and icon size slightly once you install it so you can get a lot more files listed on your screen at one time.
