The project was created months ago. It has been opened, saved, and closed many times since then. And I’ve removed unwanted audio files several times successfully, using the procedure I described. Recently, I’ve been time-stretching audio clips, and thereby creating new versions sometimes. This may be what was different this time, but I’m not sure.
All of the audio files were created within the project, and I have never imported any. I have been recording numerous takes, and rejecting many, which is why unused audio files accumulate in the Pool.
I clicked the Erase button.
Actually, just now I tried the same procedure again, and after clicking the Erase button, the following message was displayed:
“Some files are referenced by clips that are still in the Pool. These files may not have been deleted.”
Now, when I try to save, the following error message is displayed:
“The project could not be saved because the project is corrupt.”
So I’m back to the original problem.
Thanks for your interest.
