Hi all, Forgive me for coming in a little late on this. I don't really have any solutions... more like a set of comments, which may be usefull.
Macs have a compression/decompression program called Stuffit (Drop stuff for compression, Stuffit Expander for decompression). This software is free/shareware, and in all my years on a mac (6), I've never known a mac user to not have *at least* Stuffit Expander. It works simularly to ZIP on Windows machines, preserving a file or bunch of files, folders, etc etc perfectly. So, for starters, it will preserve the way that each file associates itself with it's program. As long as these files will *only* be used by Mac users, then you could require everything in .sit (stuffit) format. As a side issue, Stuffit expander decompresses HEAPS of compressed file types, from *nix, Win, Mac OS, etc. .sit (stuffit native) .cpt .pkg .lha .zip .arc .gzip .gz .tar .z .hqx .bin .pf .uu So, if your user base is both PC and mac, you may be able to settle on a compressed format(s) which the majority of Win and Mac users can open. Stuffit expander is also available for PC, although you *don't* want to force millions of PC users to run Stuffit... however if your user group is more controlled (say one office of staff), this may be an option. FILE TYPES: Just for interests sake, I opened up a Iustrator 8.0 file (.ai) in a text editor, and grabbed the first three lines for you: %!PS-Adobe-3.0 %%Creator: Adobe Illustrator(R) 8.0 %%AI8_CreatorVersion: 8 It's possible that you could establish file types by looking at the files themselves. I'd be more inclined to do a test on the file name itself. If it doesn't have an expected extension (.psd, .gif, .ai, .jpg, etc), you could reject it and ask them to append the file type, or better still ask them from a pull-down list after upload, and alter the file name yourself. The other catch in the Mac world is that I can name a PSD file something.gif, or even something.html, so relying on the extension alone is not going to be too acurate. I do commonly have problems with file-association (double clicking on a pds file opening photoshop), if the file has come from a non-mac server, or has come down through the web, or has been mangled by browser mime-types etc etc. Worse still, users' mime-types in thier browser can be set waaaaaay different. For example, IE5's default for opening .psd files is Quicktime, not Photoshop!!!!!! So, it how much pain you go through to get the file types and association right depends on: - who your target users (recievers) are - what system they run - how "savvy" they are - if your user base is a small controlled group (like 5 users in a pre-press shop) or open (like "any user on the web") I'd be trying to establish the file type by looking for an extension, looking at the file itself or asking the user for the file type (or all three!!). Asking your mac users to only upload in .sit format may indeed help keep the files preserved "as is", but may provide additional problems, if PC users wish to use the files. Sorry for the long email, hope it was some help.
