File .pes (What I need to open this file?)

[dnweLArt]

but I have too this question to other files like Tattoo02, OutfitT32, OutfitT32.of, Body22.cc, Face43.cf, Makeup26.cc. For example I think about it to copy parameters from file and paste this to file in new version hmm because 10.0 change a bit bodies or slidders of hair etc hmm
