Okay, a bit hard to explain, but i have a func witch build a treeview by searching trough a path, and then ad folders.. like in Pathfinder from Windows! But i now want, when the treeview is searching and adding items to the treeview, it should ad the information to a file, witch i can build a treeview like the one i just did, but by reading the information in the file.. Something like: [-]C:\ ......[-]Program Files .............[-]AutoIt .....................[-]Include ......[-]Documents and
