zipped modules and Macs

I’m trying to help a Mac user who’s having trouble with something regarding
modules being recognized as ZIP archives (or not) and being automatically
unpacked (or not), here:

(If you’re a Mac user, maybe try helping this guy—I’m stumped.)

What I’d like to understand is how we can combat the underlying problem,
since this seems to strike a lot of Mac users. What exactly is the problem?
What can we do to make sure this doesn’t happen?

I’d like to have answers to these questions before I start putting the module
library on the new site, as maybe there’s something we can do to fix this.

I think this may have to do with something with Macs using safari.
See this thread on bgg

and this … _zip_files.

Which Tim P posted on the wiki.

Another option would be to try a Right-Click (or Control-Click) and
choose the “Download Linked File” or “Download Linked File As…”
option. That will download the file without trying to open or unzip it.

I ran into this trouble yesterday as well with a zipped extension (a zip file with an .mdx file inside).

It appears that if a module or extension has .zip an extension, OS X’s default decompression utility will unzip the file, then automatically unzip any zip files it finds inside (that is, any mod and extensions).

It all happens pretty fast, and what you wind up with is the Images folder, the Build File, and other stuff, exactly as the thread describes. Confusing for a newcomer to Vassal, who wouldn’t recognize this as the guts of a module.

StuffIt Expander seems to not do this–only the original zip file is unzipped.

I hope there is some elegant solution to this that also addresses the issue IE7 users downloading the modules from certain sites have where the browser grabs the MIME type, often incorrect, instead of using file extension information, leading to a similar and related though not exactly the same conundrum.

It all seems to be more or less the same problem to me.

Thus spake “IrishBouzouki”:

I’m going to register MIME types for our files, and make sure that our
server, at least, reports the correct MIME type for modules we host.

There’s not much we can do about modules hosted elsewhere, other than
pester the people who put them there to do the right thing.
