I'm trying to clear some space on our server and I can see that there is quite a lot used up in the Var/Moogento folder. Are these files safe to remove? I looked online but couldn't find anything relevant.
Var/Moogento folder isn't magento's core folder, may be that folder is using for some functionality. so i suggest you to create zip folder of that folder over there using ssh and then you can remove that folder.
