Sorry if any of this comes across as uninformed etc, I'm normally on stack for code at work but I have a pi at home which I've only used for media up till now.
I'm trying to put RetroPie on it as I've bought some USB controllers. I have tried to copy the image file over but I apparently don't have enough space.
I've removed Wolfram & LibreOffice as I wasn't using these and I've seen from my searching these are 2 common things you can do to save space.
I've noticed that on the terminal if I do
df -h I get quite a few entries starting with /dev/mmcblk0p with numbers on the end (5, then 8 through to 14). What are these and do I need them all? A lot of them are pretty large and it seems like a big win if I don't...
However if I do, then what sort of things can I do to save some more space?
*furthermore: I seem to have Raspbian, OpenELEC_RP2, LibreELEC_RP2 & OSMC_PI2 at boot. I only seem to use Raspbian & OpenELEC so am I good to ditch the other 2 (guide on how would be useful too)?
I've read my initial question might be something to do with NOOBS but that makes no sense to me apart from me feeling like a complete and utter noob...
