Is it possible configure the maximum size for file uploading by type?. For example I want to allow pdf files with &0MB max size and mp3 files with 30MB max size.
I don't know of an out-of-the-box way to do this in Alfresco. Alfresco doesn't determine the mimetype of the document until after it's completely uploaded. The only thing I could think of would be to create a custom behavior that implements OnCreateNodePolicy and check the mimetype content size when a node is being created and throw an exception if it violates your sizing constraints. However, using this method, it would be difficult to get a meaningful error message back to the user interface.
