Problem w/ 4.01 and SSD's <=40 gigs, error out of space

I was able to get my WoW dirctory down to under 17GB on my SSD. Aside from the usual /cache /updates and patch files I went into /data and there was a /data/cache folder as well with about 4.8GB of stuff. I renamed the folder and launched WoW - it recreated the /data/cache folder, but it's only a few hundred MB now, not 4.8GB. I'm not totally convinced this is a safe thing to yet, I'll let you know if I find any problems. Every other post I've seen (including some from blues) say that it should take about 22GB total once patched for 4.01

Thanks for testing this. I'm definitely interested in your results and hopeful everything turns out ok. Keep us updated!

Iv never done simlinking is there a reason wow won't run from a Hard Disk with the data folder linked (with the mklink command) to the SSD?

Well forget that... the data folder is 21g lol ...

I play without sound though so looks like I could dump 4G with no problem.....

Only need textures on the SSD dont need sound there.


It seems that the 5 main files are the mpq files art, expansion1, expansion2, oldworld and world. I bet those 5 contain over 90percent of all the textures we need. Wonder if those 5 could by symlinked (mklink) to the SSD.

Sorry for a slow responce - been off-line for a week or more.

I will say that I didn't have any problems deleting my /data/cache folder, but it does seem that over time it just creeped back up to the original size again - this did seem to take several weeks to get back to full size though, and I can't say that I had any issues. My lag is always much lower than what most people report anyway - combining that with the stability issues the xpac caused I'm not really sure what the root cause may have been.

My guess is that it slowly downloaded or unpacked some stuff as I went from zone to zone. So at most you could possibly save a little space if you just don't visit outlands (or maybe northrend after the xpac), but I'm not entirely sure that it wouldn't just download it the background anyway. This may also help with some of the issues installing to a SSD where you have plenty of room for the installed patch, but not 2x the space which is what seems to be required to install it.

Overall I don't think this hurt anything, but it didn't seem to help either. I'm back to 21.8GB for my WoW folder.
