Hi, I use explorer and Poser File Organizer. I got myself Poser File Organizer because my Runtimes were becoming too huge to navigate AND I was spending ages searching for stuff that I knew I had somewhere. I also was not very confident of simply manually moving stuff because there are so many referenced files (e.g. deltas, textures, objs, etc). The biggest help we could have is if ALL product creators used a helpful file and folder naming convention. Since this isn't going to happen, all you can do is bite the bullet and reorganize you own stuff. I have broken my two orginal runtimes (default and Downloads) into (Animals, Buildings & Settings, Effects, Natural, Props & Furniture, Runtime [characters i.e. V3, S3, M3 + All their clothes], Sci Fi, Vehicles and Weapons). Anyway, Poser file organizer has a slightly terse user interface but, once you get used to it, the utility really helps with moving all the related files and references around to other runtimes. One word of warning if you do use one of the poser file utilities - start out small, learning on a pair of test runtimes before you commit to any huge changes on your actual runtimes, because some of the options could leave you with many broken poser items. The PFO option to convert rsr (which you cannot see) to png (which you can preview) will also help when you use explorer to make your new folder structure and for renaming folders so that they are easier to navigate. HTH, Jovial.
