When I am working with a file in Audacity, I choose the option "Save Project As" as a file I want to save premastering as a backup in a file that I use to backup chapters before mastering. Correct me if I am wrong, but I would have to close out the screen, and go back to the original file I was working with to continue on to leave the backup file in the new file location as it is, with no further changes. If I use the "Save Project As" it would rename the file I have as the backup one, and if I did anymore edits on the file that was opened and "Saved As" it would make changes to my backup.
It is the most confusing part of this whole thing. I think that it would be great to have the option "Save Copy of Project As" to give the option of saving a copy as the file stands, but continue on in the original file instead of closing out and reopening the original. If I am totally wrong about this let me know. I am a fairly new user
I really hope I am clear.
