Yes, that will work fine.
I've been running BT3 off a fat32 formatted sd card. I wanted to move the files onto my ssd which is formatted ext2 would that work?
Yes, that will work fine.
oops sorry, you are correct. The problem was the data directorys name, on the fat32 volume it was "bt3" when I copied it to the ext2 volume I found it was necessary to rename it to "BT3" and then it worked.
