My PT session for a short film has several audio tracks, and at some point I imported an OMF from the foley department. I worked directly from this OMF (maybe the problem started here?) with editing, processing, etc.
Now that I was saving a copy of the session to another location, I was surprised to see that it required around 250 GB, where the Audio Files folder only was 16 GB. Not knowing where the issue was, I still made the copy.
Later on, checking the Audio Files folder of the copied session, I had over 400 instances of the OMF, all with the same creation date and most of them with the complete size. It seems that it´s an instance for every clip that was not processed.
For trying it out, I moved all OMF files, except one, to another folder and tried to open my session. ProTools still needed to locate the OMF´s or else the audio clips associated with it, would be stated as missing files. I restored the OMF´s to the Audio Files folder, but ProTools is still not finding them.
Why is ProTools doing this and could I have avoided it by duplicated the OMF tracks and work from the copied audio clips?
I have ProTools 10.
