yes while in file explorer on the titan or any other ppc just hold the stylus down on the file it will pop up just like right clicking on a desktop just select the delete option. Or if you can't get that to work just click on the name not the icon for the cab then the lower right hand soft key will pop up a menu for renaming copying/moving and of corse delete.

In the future if you install a cab and don't need to keep the cab file afterwards its a good choice to set the option to delete cab files after install option. Not quite sure where the setting is for that but i'm sure someone else can help you with that.
