My first post. I'm transferring to Linux Mint from Windows and everything seems to work well except when I save an X3g file Linux is showing it as a Text file. My Quiditech printer does not register these files - they simply do not show up in the list of available files to print on the SD card. For some reason some of my old designs (from windows days) show as text as well and similarly do not show up on the printer but I know for a fact I have printed them before.
I suspect this is a Linux issue but would appreciate any advice.
Many thanks in advance,
