probably not the cr2 and what ever else files you deleted would have given you clues about what obj and textures you needed to run that particular character, hair, prop ect. without some file leading the way about the only thing I would know of would be to uninstall Poser and see what is left, take those files and archive them and when you need a particular file go to that archive and reinsert it into the correct folder. Sounds like a long drawn out process. Just a thought but maybe before deleting any more cr2's or whatever you find out what other files that cr2 requires and make a dummy runtime and then zip all the files refered to into that dummy runtime. CDs are pretty cheap, why not next time move all the files you are going to delete onto a CD. Right now I'd guess you have weeks of work in store. Try going into search and do each left over obj and texture and find out what files call for those, if nothing does feel free to delete files. Good Luck
