The default quota on uploading files is 50mb per file and 5 GB total space.
That is to say that technically you are allowed to upload files as large as 50mb. And you have storage space of 5 GB.
However attempting to upload files much larger than 5 mb is very risky. You are often going to run into many problems in the attempt. This is due to the nature of HTTP uploads in general and not anything specific to this site.
If you are planning on often uploading large files, such as sermon audio files, it is a much better idea to use what is called ftp.
Inorder to do this you need a special account set up for you. Simply email me letting me know what it is you would like to do. I will set it up for you: sozomai@hotmail.com
