Eliminating un-used parts from mods?

[hansman1982]

With .20.2 I have been having issues with extreme lag and the game crashing with certain mods added (DAMN YOU NOVAPUNCH). In reading another thread, it appears to be some of the bigger mods are eating up massive amounts of memory thanks to their parts.

Is it possible, to go into mods and remove the parts I don't use/want? For example, since I have the stock aerodynamics, I NEVER use fairings. Can I just go in and delete out all of the fairing files from the parts folders and hope that helps with this issue or will that cause other crashes?

Also, could I simply edit these files to make them more useful (I want to try giving fairings a negative drag factor so they are useful) and is it as, possibly, simple as tweaking the .cfg file?

Yes, to both - although of course feeding negative numbers into a field expecting positive ones isn't guaranteed to work.

Be careful with that negative drag, I've suggested it before, apparently not good consequences. Like, moving forwards without engines, consequences.
