can't load .rmbackup ??

The rmbackup is for Rig Manager, I believe, hence the ‘rm’

Well Pedro, the former file type is "manually" imported via USB stick into the Kemper and the latter into Rig Manager via its backup / restore menu.

EDIT:

Andy, you beat me by the difference between "a moment" and "a minute", according to the forum software.

‘Great minds’ Nicky!
