Cut and paste sections of tracks on edit page

[markus44uk]

I have noticed that if I highlight and cut a section out of one part of a guitar track and then paste it elsewhere in the track, I am actually copying the entire track over again. This is taking up large amounts of disk space and I was wondering if I am doing this wrong.

Basically, I am trying to cut or sometimes copy a guitar part section of a track into another location in the track (to compensate for a poor performance or a bad note). I would have thought that highlighting a section of a track and then copying just that section would only create an additional audio file on the HD that was the size of the cut piece rather than the entire track.

HELP!
