HOWTO: How do I delete ListPro files, lists, or items on my Windows Mobile device?
If your Windows Mobile device has a touch screen:
Delete a file, list, or item by tap+holding on its name; you will receive a context menu that lets you edit or delete whatever you tapped on.
If your Windows Mobile device does not have a touch screen:
Highlight the file, list, or item you want to delete and press Menu -> Edit -> Delete.
