What is the easiest way to transfer files from (and into) my pc to(from) my windows mobile pocket-pc (Tytn II) just by using the wifi I have at home?
Is there any simple app that I can install on the pc or the pocket-pc that helps me do this?
The Windows CE (Pocket PC) version of Total Commander has windows file sharing access in it, I think you access it through the \Plugins\LAN folder that is visible in Total Commander. You may have to add a server first by specifying an address (machine name) and login credentials (standard windows username etc) but after that I think it works quite well and you can access the shared files with relative ease.
Total Commander is a very capable file browser on WinMo, much more useful than the builtin Explorer.
