I'm worried about having lost or corrupted iMovie files, and I'll start by telling you what I did: I upgraded my MacBook Pro from Lion to Yosemite with a clean install. How did I back up my movies? I clicked and dragged "movies" out of my Movie folder onto and External HD. It took an hour. After I installed Yosemite, I clicked and dragged the Movies file back into the Movies folder in my MacBook Pro. Now I couldn't open iMovie 09 so I upgraded to iMovie 10.0.6. During this install I got this message (I paraphrase): iMovie is unable to locate all parts of project files and or may not be able to incorporate all your other videos.
These are my questions:
1, Process: Did I do anything wrong in that process of clicking and dragging that might have corrupted my movie files?
2, Click and Drag/Copy and paste/File and duplicate: Is there a best practice way of moving delicate movie files? And are movie files in fact more "delicate" or breakable than writing files?
3, File duplicate finder: Is there a way to check my current movie folder against the original on my HD to see which files could not be initialized?
4, Rewriting Movie Files: Does iMovie rewrite the movie files so they can no longer work on a PC or with other movie programs?
5, Movie File Corruption Check: Is there a way to check if my current Movie folder is corrupt before I (one day in the future) upgrade to iMovie "12"?
If you can answer even one thing I'd really appreciate it
