I am talking about a Poser 4.03 fresh installation. In the Poser 4 folder, several files are installed, but apparently, only Poser.exe is needed to run Poser. You can, in fact, delete all other files, and Poser will still start and work at least it does for me). So I am guessing what the other files are for. Some are or should be obvious, like the unPoser4.isu which should be for uninstalling, or the regPoseri.exe to register, etc.. But some are not so obvious and so here I ask about them, which is their function: asi32_12.dll imageioEngineWin.DLL (this, and the following one, should be for input/output routines, although they don't seem to be vital for the application) imageioUtilities.DLL MtsWriter.dll ASIFONT.FON (what is this font for here, and why isn't it in the font system folder?) ASIPORT.RSR asifont.map Poser.rsr (what kind of resource is this, if it's not needed to run Poser?) Poser.dta
