How many files are created for the cache

We have a server that is limited in the amount of files that can be stored.

We have a pretty large page with a lot of filters that are currently filtered locally with JS. We would like to switch to serverside filtering and also cache all these filters and combination of filters.

I have the fear that we will get exponentially growing file usage by caching all of this. So I was wondering. How many files are created per items cached? Is it 1 item = 1 file for the cache, or how does the math work?
When I go to the preload page we currently have this amount to cache:
?action=wpfastestcache&type=preload

homepage: 1/1
customposttypes: 0/2068
post: 0/0
attachment: 372/2258
page: 28/28
category: 0/1
tag: 0/1
customTaxonomies: 0/1271

So would this result in 5628 individual files? Or is some stuff combined into a single file?
We have around 4 fields with up to 20 options for filtering. That would be 20^4 = 160k. When caching these combinations, would it create 160k cache files?

I hope this question makes sense, if something is unclear, please let me know and I will elaborate.
