Thanks Ingolf, I found the rigs folder after double clicking on the .tar file! (Does that mean I have decompressed it?)
When you say "re- compress the content of the whole backup folder again, not the folder itself." Do I highlight all the contents of the .tar folder and click compress?
I'm still confused as to why I would have to alternatively delete all the rigs manually on the KPA before doing a factory reset as surely the whole point of that is that it would wipe everything that is already stored on it?
Also, if I want to add back a few of my favourite profiles from the existing rigs after I have reset it is that easy to do? (I'm guessing I just drop them back in the shared folder?)
Again apologies for the computer illiteracy, really appreciate the help though!
