Cresotech PocketLANce 1.10
the author of this app says:
Cresotech PocketLANce is a unique application allowing PocketPC users to browse and manage LAN resources on their PDA devices. Now you can work with corporate or personal LAN resources using your PocketPCs. This application locates, retrieves and moves/copies network files via conventional ActiveSync connection, network card or even mobile phone/modem.
PocketLANce also opens far-reaching possibilities of remote mobile network access via mobile phone or modem using RAS (Remote Access Service) or DUN (Dial-Up Networking).
Starting from version 1.05, PocketLANce can work without ActiveSync connection when using network cards.
