... Scratch my request to the gurus out there. I figured out how to anonymize my fields using existing MC tools.
As a test, I did the following:
- Cloned my largest library on a laptop, disconnected LAN to make the media files off-line, disabled tag writing and switched Auto-Import off.
- Created an "all media" view scheme. It displayed about 60,000 files.
- Selected all files and pasted
=[Duration] [track #] [Bitrate] [Date] [Filename] in the album field in AW. This created a new unique album value for each file (about 50.000 of them are audio).
- Processing took about 10 minutes. The new values appeared in about two minutes and the rest of the time was apparently used for composing and writing the physical library files when I browsed away from the view. The resulting field (album).jmd file was a bit over 5 MB.
I guess you figured out something similar.
