I'm pretty sure that was just a typo, and he/she meant 'by'. LOL
As has been said, any link your browser doesn't understand will be downloaded. Here's another example.
[list=1] <a href="index.htm">Index Page</a>
<a href="thing.php">PHP page</a>
<a href="pic.gif">An Image</a>
<a href="pic2.jpg">A JPG Image</a>
<a href="stuff.php">ASP Page</a>[/list=1]
All these links (in blue) would normally be opened in the browser window. To download these files a user would have to right click on them and select save as. This is because they are all web pages or images that the browser understands.
Number 1 is a standard HTML page, number 2 is a PHP page which is converted into HTML by the server, so the browser just gets HTML again. Number three is a GIF image such as might be displayed on a web page, and number 4 a jpg that you might find on a web page. Obviously the browser can display these. And the last one is an ASP page, which, once again, is converted into HTML by the server.
Here are some files that would download:
[list=1]
<a href="compressed.zip">Files</a>
<a href="prog.exe">Program</a>
<a href="splat.tar">A tarball</a>
<a href="link.dll">DLL</a>
[/list=1]
None of these (red) files would open in the browser window, because the browser dowsn't understand them. Number 1 is a compressed file. This contains many files, so cannot be viewed in one browser window. Number 2 is a program. This would run in its own window. 3 is a tarball. These are sort of like .zip files, and number 4 is a 'dynamic link library' file. This might be associated with the program, and doesn't do anything at all on its own. If you clicked a link to one of these files, it would download. Since .zip files download automatically on clicking, you can package files that open in the browser window in a zip and it will auto download.
I hope that helped answer your question. If not, just say so.
