There is also a difference if you are burning CDs which can be used on both PCs and Macs. Almost everything I buy which has come on CD was burned on a PC using standard copying method... and that means the file names are 8.3 DOS formatted... not a problem if the files have obvious and separate names, or short ones. If the files are something like this: Vicky_blouse_1, vicky_blouse_sleeve_trans, vicky_blouse_2, vicky_trousers_with_spats... they will appear on the Mac as vicky_~1, vicky_~2, vicky_~3, vicky~4... and we get to second-guess some stupid Windows glitch. [Note, you can get a Joliet decoding thingy which will look at a standard-Windows-created CD and make all the names right again. Follow the links at the VistaInternetProducts site. This has affected CDs from them, PhilC, and Cal, but not Brycetech or DAZ.] Carolly
