This link is for the P3do explorer. I use it to move and delete files, change folder names, what have you and have had no problems with poser then reading the files afterwards. It's a free program too so that's great! For m3 and v3 I got sick of the files, so what I did for each was load them up add all their inj files then save the pz3 file. I then deleted the rem mor files since I don't use them anyway. Now I just have the folder with their inj files; and load up the pz3 when I want em! I think the files when you try to do it the way you mentioned overwrite each other due to being the same name, I could be wrong, but I remember something about that too. Honestly though I had the same problem as you and using the P3do explorer has made it easy for me to locate folders and preview what's in each and saves me the time and energy of going through each pose file in poser. Hope this helps some. Organizing is not my strong suit but those pose files go on forever lol. Smiles to you!
