It's easy for me. After my last BIAB & Reaper installation I removed almost all of the VSTs I'd downloaded and transferred across a decade or two.
I retained all of the Reaper native plugs as well as about 10 others that are part of FX chains I've created or get semi regular/specialist use.
PSP Vintage Warmer 2, Density, a few Modern comps, the Deathcore decimator like comp, Vola2 for vocal levels, a Leslie simulator and such like - most of which were freebies.
I did keep the few VSTis/samples I have but there aren't but a few of those.
Easy to keep relatively tidy.

Cheers
