Ohhhhh my God thank you so much for replying.
I think I might keep my lunch down now. These files are VERY important.
Their music files, and some of them we're by artists the studio PAID for.
So, yes these are VERY important. These are post-production too, so a lot of work was already done to them.
I'm still scared to see if they come back, but thanks for pointing me in the right direction.
NOW, why doesn't Apple warn you when your about to delete a file where 90% of the data was in use?
They don't give much heads up.
Thanks again though. I hope good luck finds you this week.
