Seems like the media manager / collect function doesn't like the "&" symbol :/
Created a comp with a lot of clips, hit 'collect media' .
Copied the entire folder generated on my SSD, copy the entire folder back over on the M2 ssd of my gig laptop.
8 clips missing that should be there.
I think the "&" symbol creates some problems, the original file is named "Box&Wire.mov", but on the gig laptop the missing file in media manager is named "Box&Wire.mov"
Also sidenote , relocating files is way harder in Arena 7 as in the previous version.
It's like the current media manager only looks for other lost clips in the same folder when you relocate one specific clip, while in the past you could it just show a main folder and it searched its way through all subfolders locating all that's missing, was way faster !
