Which kodi folders/caches to move to harddrive


I used to have raspbmc on my raspberry with an usb harddrive. My SD card has only a size 2GB, so I used to move the .xbmc folder to my harddrive and created a symlink in my home folder.

I did this, because of movie posters + other stuff xbmc caches over time I would exceed the size of my SD card.

Atm I’m setting up OSMC and I would like to know if you think this is a good idea. Or if there are only some folders of kodi which I would need to move to the harddisk.
