Hi Phillip,
You're right, it was a foreign format for MAC. But with the advent of stuffit expander, you could handle other zip files without a remnant or fragmentation on OS 9. This is what caused me to wonder if there was a fundamental difference between what OS X terms a zip file and what windows and drop stuff term a zip file or if there was something different with one of my machines. From the previous posts, at least one other person has had some strangeness with this.
If I want to send a zip file to a non OS X machine, I go back to the old drop zip or use drop stuff and create a self expanding stuffit archive for windows. I have never had problems with the self expanding archives with the exceptions that
a. some email programs give warnings because they are a .exe file.
b. some corporate systems will not accept any .exe file

You didn't mention That. zip was a foriegn format for OS9 until the program you mention came along and then about the same time Aladdin (Allume) came along and figured out how to do zip.

So there was no encoding involved as in sending an Email attachment.
Now if I take the same file on my OS9 machine and use DropZip (forget which version), I can compress and decompress without these remnants.
Note that sending files archived with .zip in OSX to another OSX machine does not result in this. I have sent files back and forth to a couple of my clients that way and they never see a remnant. All works as it should.

Sounds like the person on the other end didn't encode the file using AppleDouble which merges Mac's Resource and Data forks into one merged file.
Mac has always youed a two fork file system a File is actually made up of two files locked together. A resource fork this tells the Mac which Application is supposed to open the File. Andthe Data Fork which as it states contains the Data.
This was and is still the reason why its difficult to create a virus that seriously affect a Mac File. In most cases on OS9 all you needed to do to get rid of what viruses out there for Mac was simply rebuild the desktop.
But, it cause minor problems when sent to PC people becase they receive two files. If they open one they see gebrish (the Resource file). Then if they open the open the other The see the Data. In the older days Word used the the resource fork to keep the formatting and line breaks. So if you openned the Data forks you might have to reformat and re add line breaks.
AppleDouble was designed to merge the two files into one Data fork that PCer's could use.
OSX still uses the same system but now only pointers to what application is used to open the file is in there. So The Data fork contains everything the PCer needs to open and view Mac file.

I have seen strange things with the built in archiving for OS X. Decompressing on a classic os machine leaves three folders:
An enclosing folder OSX folder Another folder
and two files one in the OSX folder and one in the other folder.
I have not explored it so I do not know if it is just something local to this particular machine OSX 10.3.4 then OS X .3.8
Decompressing on windows does not appear to be a problem from what I can see.
HTH

Not for me. Routinely zip up multi megabyte files.
Take care with OSX archiving as it is a proprietary format which I do not think works when you try to decompress under another OS !
Works for me daily between OS X (10.3.8) and Windows XP Pro.
