@Jimmy - I believe I saw before that you can go to Content DB Maintenance in Daz and export your user data through there, which lets you save your custom categories.
@Szark - I did the same thing with my Daz content. I have Daz in E:\Program Files\Daz Studio 4, and all of my content in multiple libraries held in F:\Daz Studio. Nothing is on my C drive that doesn’t need to be—only the OS, security software, and drivers go on it as it’s an SSD drive and I prefer to keep it clean for performance reasons. It irked me to no end that I couldn’t customize the DIM installation. No option, or anything.. just straight to C:. >.>
Adobe presets bug me for the same reason. I can add in multiple Plugin folders, but not Presets folders? Meh.
