Hi. I just finished installing and configuring MacOS X Tiger and all of the software that I plan to use. Here's my dilemma: Say I'm working from QuarkXPress in MacOS X. I save the document. Being a Windows user (not yet former, as I use PCs at work), I give it a file name and append the ".qxd" extension. It saves. However, when I look at the file in the directory listing, its icon shows up as a regular piece of paper (when I worked under MacOS 9, I was used to seeing the program's icon assigned to a given document). My concern is that I can't tell visually (except by extension - are extensions even necessary?) what program created what file. Is this normal? Also, can I save files in MacOS X, put them on CD, and open them in MacOS 9? BTW, hard drive is formatted as "MacOS Extended (Journaled)" (or something to that effect - can't remember right now) and working out of MacOS X exclusively (no classic mode). Any help would be appreciated. Thank you.
