I recommend Poser File Organizer (RMP) and P3d0 Pro (Senosoft) also. Between them those 3 utilities handle all of my Poser file/library maintenance needs. There's some overlap of functions, and differing function/workflow philosophy, but I've found the authors of all 3 to be really receptive to input from users. I've contacted all at different times with bug reports and suggestions and found them all to be receptive and eager to improve their products. The newest P3d0 coming out soon, will even be able to handle the P6 compressed OBZ files. I used it recently to mass-convert all my thumbnail RSRs to PNGs in one operation, deleting the RSRs at the same time. PFO and CRPro have more overlap in function, but each can do things the other can't as well. I really recommend all 3 to anyone needing more order in their Runtimes. btw - I just got an Email from Yarp (P3d0's author) today advising me of a completely new, more stable file management engine in the newest version (1.7.7 r2) awaiting release this week.
