I have ASUS T100TAL laptop. There are only few available space on hard disk. Can I Install Unity 5 on SD card?
Assuming you are running windows; As long as the SD card is always mapped to the same drive letter and has sufficient space, I don’t see why not. Performance may be another issue entirely. Still, I’d say give it a try. (please post back results- I’d be interested to see if practice actually follows theory, in this case)
