Thanks Nick it makes things a bit clearer so name are not enclosed in MIDI dump but only in the XML 

So far I'm saving the presets in Documents/Sysex. 

When I open my own back up from this folder with the editor it does not display any names

Shall I conclude that I have to save my back ups in the library and not in my documents, open the editor to change their names and sort them and finaly resend everything to the TF

(not sure if I'm completely clear on this – just trying to play a bit with it)

Cheers
