How to erase video-file on miniMAD sd card?
Should this not be a basic operation from the mad mappers " export to miniMAD interface" ?
And how to format the SD card correctly? Is it the Apple PI baker, that does the right thing?

There's no need to manage anything by hand on the SD-card.
MadMapper will manage the files for you by removing the unused files during the export operation.

Don't try to format the card yourself either.
You can backup and restore your SD-card using Apple Pi-Baker.
