I boot normally into LiveUSB. At Exit ― I'm prompted to create a SaveFile.
I created it on a different external HDD with NTFS at /mnt/sdc1/FossaPup/fossapup64save.4fs
. When I boot into LiveUSB ― it doesn't use the SaveFile. Am I suppose to do something else?
There is free-space on the USB card ― but it's very slow, so possible to save it there, but not preferable.
(solution here, following the advice here, with details another comment after.
