Compressing and decompressing a file -- sorry a folder

[Matt Denton]

Hello all,

Just a quick caveat: in OSX remember that some files can be a bundle 
and actually a folder.  If you try to compress then decompress this 
file, it won't work.   (I think Rev has some notes tucked away 
somewhere about this, not sure where, maybe in Dev Guide folder notes?)

Anyway one quick way to check if an Application is a bundle (ie 
actually a folder in disguise) is to control-click on it from the 
Finder.  If you see a 'Show Package Contents' then it is a bundle (are 
all Mac OSX apps bundles or just Cocoa apps?  Not sure here).

So don't get trapped as I did: I thought I'd hit a miracle when a 10Mb 
application compressed down to 10K, now that would be nice.

Might be good for dictionary inclusion and/or Development Guide recipe 
Rev team?
