Dizzie, The Joliet setting will allow you to read the CD across platforms (PC and Mac). I'm not sure if the other setting will do so. The problem with the non-Jolietted stuff isn't that the Mac won't read it, it is that the file names get shortened to the DOS 8.3 convention. CDs from a few respected merchants in this community need to get converted or else all the textures will be undecipherable. (and we know about Poser and not finding textures) Another issue with CDs is that the rewritable ones can lose the piezzo charge so they become unreadable. So I only use regular CDs. Carolly
