JV, I store my PZ3's in another directory and on another drive. The biggest part of my Runtime directory is the texture directory and much of that is that I save most of my revised textures in Tiff or Bmp format as jpg formats lose resolution with each modification. With Poser5's crankiness with textures, it's dangerous to move texture files around as I can never remember all the places any given texture may be referenced in a library file. I run CorrectReference on all new library items.
