lost files

:( i lost a lot of files to my film and other things. pretty sure i know what happened. one morning while working on one of the somali pieces and i deleted stuff to make render space believing i was backed up. there is an option in final cut, i thought it only eliminated render files - it was far more. i have been able to recover a fair amount but only beginning to realize how much is gone. i was just going to go to bed, but instead i will start the process of recreating all that's lost. i fear it's hundreds of hours of work.
