On copying files from USB storage to my computer one file in one SHOW folder could not be copied / backed up. SHOW.DAT
This files key function is I believe to index the screen name you manually give the SHOW folder to the sequential folder name created by the mixers filesystem.
The file just came up with an attribute error message at point of copy. No other files had any issues.
On thinking about this and some earlier testing Id been doing I believe the cause of the corruption was attempting to save an existing Show without a USB stick being in the drive.
Have nothing conclusive on this but just thought Id put the observation out there in case it assists anyone.
Cheers
