Recently released liveries for the 32NX have quiet some size and applying just 10 of them took more that 1 Gig of space . Dont know how much space will be required once 3rd party a/c start coming 
Is there a lower size/res option also available somewhere?
Some livery developer choose to make high quality liveries (4k or 8k). These are big. If you don’t want these, try to find lower resolution liveries.
Yeah you’re pretty much at the mercy of whoever is developing/sharing the liveries. I prefer the higher res ones. Excellent details.
Are you getting your liveries from here? I’ve seen some low-res versions of some liveries on there… might be worth a look.
Yes, got them from .to, will check out again - first ones were all high to very-high res.
The liveries coming from the Livery megapack tend to have lower res liveries. So you might want to check that out if you want to save some space.
I have 15 gig worth of liveries. Lol, and I only have 75 of them.
