One of the items of software mentioned by Nerd3D (see previous post), was called PoserEd. I’d never heard of it before. Turns out it’s for hand-editing Poser saved files. I knew there were several free .CR2 editors, and sometimes you can also just use Notepad++ to take a peek.
However, Nerd3D was re-purposing PoserEd into something closer to my heart — a where-the-heck-is-it content finder, as you can have it show the linked file paths and suchlike.
Where to get it? Seems to me that PoserEd must actually be short for Poser File Editor 3… which unfortunately is no longer sold. A comment elsewhere appears to indicate that 3.3 was the last update.
I also found a comment that said that Netherworks’ Creator’s ToyBox does something very similar, re: how Nerd3D was using PoserEd.
