From the developer: ""A real network explorer for Pocket PC 2002. Map multiple network share folders and printers for Pocket File Explorer. Browse and open remote computer files in Pocket File Explorer with Ethernet card, wireless 802.11b card or dial up network. Play MP3, big file size movie on your network in Windows Media Player. Enhanced Ping can resolve the local network computer name and also remote computer MAC address.""
It does exactly what you want, it provides real wireless network. I don't have my 2Gb MicroSD card yet so I can only use the 64Mb storage built into my Orange SPV 3100. But I can browse and view 60Mb MP3's and 250Mb videos. It also lets map to network printers.
I couldn't get it to print on my printer to print. It rolled the paper in and tried but it never actually worked. Even if it did work it would only print plain text with no formatting. But I don't care because I can open huge files!
