Reducing folder size

My WoW folder is around 200GB, I have TBC, MoP and Classic also installed. I’ve noticed the Data subfolder is 194GB. Can I do something to reduce its size?

How long has it been since you did a fresh install

About 4 months ago

I have only one version installed and its 135 gigs. Each version is going to add on to that . $ months is not going to collect a lot of things that are no longer relevant

Yeah, it seems 200GB is expected with all versions installed. Thanks!
