If you run a Drupal site and want to upload big files you may have run into the default file size limit of 1 MB. While this is probably fine for most blogs it is way too small for most intranet deployments.
The limit for PHP is by default set to 2 MB for file uploads.
To increase this to 10 MB, add the following to the .htaccess file in your Drupal directory or to the Apache site definition:
php_value upload_max_filesize 10M
php_value post_max_size 20M
