PS 1.7.8.2 big database space problem

[prestaseller]

Good evening everyone. I have a big problem with my Prestashop site. The inode limit of my hosting is unfortunately very low, 262,000 and I'm struggling to reduce them but I promptly reach the limit and nothing works anymore. The solution of course is to move on to something else, but I've already searched and haven't found anything that fits my situation.

So I would like to find a solution to stay as they are, for example I would like to find all those useless files and remove them, does anyone know what can be removed from the database or via phpadmin or via ftp, which can be done without, avoiding damage? I have prestasthop 1.7.8.2

I only know img/tmp and var/cache, the latter is a palliative because it promptly recreates the thousands of useless files, and I don't know how to prevent it.

I hope for a miracle.
