"but for Poser libraries, I put the "ren *.pz2 *.cm2" command into a batchfile called PZ2CM.bat" Leather, is this something that is done by creating a text document, typing in a string of code, and then saving as .bat? Could you provide the code to use? I sorta never really did officially learn DOS.... semidieu, I think that pre-Poser 5 users with Pose runtimes over 256 folders is an epidemic, and I for one would LOVE to see a little GUI app created specifically for Poser to convert directories full of .pz2 files into .cm2 files. What I would think would be desirable features would be: 1)Have it first launch prompt user to browse to root Poser directory, so it would have awareness of ProPack or Poser 4 Pose and Camera directories 2)Have it open itself to Pose library on all subsequent launches so you can get right to browsing for the pose subdir you want to work with 3)Give it an "explorer type" window, so that a dir with .pz2 as well as .rsr and .png can still be quickly used to select .pz2 files. Perhaps include a "select all .pz2's" button? 4)And possibly just to be Awesome on multiple levels, after conversion, an option to "Move dir of converted files to Camera library?" with a simple click of a "Yes" button? Tbis features list, if not prohibbitive, would I think make a sweet little application that most ProPack users would be proud to have alongside thier UVMappers, Objaction Movers, MAT Pose Editors, STOMPs, etc etc :) From a scripting standpoint, is this too complicated/time consuming an application to justify being a freebie?
