It's a folder I created, on my HD called Poser QFix. All it is... is a copy of just the program files from a clean,fresh install of Poser(plus patches,and memory patches). No runtime,read me's,or PDF's,and it is only 14.5 Meg. Awhile back,I had the "can't open Poser" problem,the "not enough space(or memory)to render",the large renders that stopped before they were done, and the general slow down of Poser. I found when those problems happened,all I had to do was DELETE the program files inside of Poser,and replace with the fresh ones. Now I don't wait for a problem, I just do the delete/replace about every two or three weeks(takes 30 sec),and consider this as routine maintenance. I can notice Poser runs faster and smoother right after doing this, and I never, NEVER, have these common problems anymore. This goes along with what Steve said about the rsr files,but Ive sometimes noticed a change in the Poser exe,and dil file size alsowhich indicates possible corruptionso replace them all. BTW>All your preferences and settings are located in the runtime folder,so these are not effected. Hope you find this useful. SWAMP
