@ModHunter I know this thread is old but like others who have read this, I to have replace cars and experienced random crashes and couldn't for the life of me figure out why. Thank you so much for making sense of this and solving my issues! Definitely very helpful information.
Edit: I have a few questions as I am I filtering out the large car files.. Am I looking to keep the entire car file 20MB or less or the individual files ie; .ytd, .yft etc? Also, I have seen tutorials on splitting .ytd files however, I am wondering if there is anyway to compress any of the files?
Thanks again for all of the info!
