do we have to copy all files in the songfolder back when we want to redo the backup?

[istyle]

in cubase
do you do it other way when you wanna edit the backup?
i think it's best to delete files like nuendo's function "delete files not in use"
cos each songfolder can go up to 500megs
thnx

I don't quite understand your ?, but if you are asking if you can delete files in your song folder that you are no longer using?
Yes. Just delete what you don't need & re-save your file. Cubase will no longer look for those files if the song or arrangement has been saved after the edit.
