I was wondering how do you go about having a queue system for files so that
people have to wait for a slot before downloading a file so that everyone
does not try and grab it at once?

Imagine CNN and Google having a queue for viewers! Mayhem! You're
negating the purpose of the Internet if you want to queue.

If you're speaking of ftp stuff, you'd need a program to handle the number
of simultaneous logins.
if you have cpanel, look for "ftp manager", that will allow you to set the
controls.

You'll need to assign an ID to each user that attempts a download, store
that in the database, then have the page they're looking at refresh
every so often to check whether they're able to download. You'll also
need to consider what happens when your visitors leave without
downloading the file because they can't be arsed to wait.

Have a script that locks a database table or another file, echos out
the file for download after setting correct content-type headers, then
unlocks the table. Anyone trying to download while the script is
running will wait at the lock until the first script unlocks it
(automatic on exit, in most systems).

Not useful (at least, not without modification) if
you want more than 1 but less than X simultaneous downloads, though.

I'm not sure that it's particularly useful at all, though.
