Upping PHP's maximum file size upload limit:

Your problem: the file upload settings page on your Drupal site (if you've found it) is telling you silly PHP won't let people upload big files, to wit:

Your PHP settings limit the maximum file size per upload to 200 MB.

There's two places that this has to change in your php.ini file; this can also be set in your settings.php PHP initialization variables.

We at Agaric like the sledgehammer - nay, mechanized battering ram - approach to fixing niggling little problems, so here's what we're going to make those sections look like:

; Maximum allowed size for uploaded files.
upload_max_filesize = 200M

and

; Maximum size of POST data that PHP will accept.
post_max_size = 400M

Here's what you have to do in command line shell commands, which is sort of like poetry...

cursor keys cursor keys...
cursor keys cursor keys... backspace (which saves and exits from the vi text editor)
(which restarts Apache, in our configuration, which, you'll note, is Apache 2.)

Now go to admin/settings/uploads ...

Your PHP settings limit the maximum file size per upload to 200 MB.

That's more like it!

The Agaric way is not recommended for mortals, sane people, or even deities or insane people with weak stomachs.

Agaric already covered this subject on this page but here we cut to the chase!
