The largest file size is 25 MB.
The media library can hold any file type except code – html, css, etc.

The plan is to connect the media library to a cloud service – the cloud service has recently changed to a S3 system and I am having difficult getting the connection just right.

When connected, access to the media library files is through the media library but the actual files are stored in a cloud which allows us to upload as much and as many files as we want without worry of slowing down the server.
