classic I'm using NTFS but when I first got PBooost I had the problem with locked folders, then a few weeks later Howard brought out CorrectReference & it solved the problem, it also speeds up poser when loading textures & figures with textures already assigned. ernyoka I should've said if you have a big runtime you should do it a bit at a time, the only folders that really have to be checked are character, pose, hair & props. you only need to check the others if you've put mat poses in them.
