iWeb - How or 'repackage' and unpackaged iWeb Domain file

How to Repackage an unpackaged iWeb Domain file ?

OK this will make sense shortly. But first - I know what the Domain file is and what it does...

Situation

So I want to help a friend update her iWeb site. She lives overseas, so I suggested she FTP her domain file to my server. My plan was to download it from there, do the tricky stuff then send the updtaed file back.


Problem: it is no longer a single file, but appears as a series of files and folders, as one gets when clicking "open package contents"

In the absence of a

"put contents back into a package and call this package Domain"

command

What can I do.

Or is there a way of "repackaging" files in OSX

Hope this makes sense



PS - FTP-ed 'cos was too big to e-mail
