I'm not completely sure what you are asking. However, in case you don't know the regular Pronto files (extension .ccf) are different from the ProntoNEO files (extension .ncf).

A program called NEOedit is used to edit the .ncf files (and send them to your Neo). That should have come on a CD with the remote, and you can get a newer version from the Philips pronto web site.

As far as I know, there is no reasonable way to open a .ccf file in NEOedit. For that you need ProntoEdit, which will not connect to your Neo.
