I havn't found any of these files, and I even did a file search. However I did notice that these filenames look like the format used by PBoost (which I removed from my system right after getting P5 and a dedicated hard drive). By any chance are any of you using PBoost? Could these be swap files being left behind by that program? mike P2 500mhz Poser 5 SR2B4 WinXP (recently upgraded) Running fine
