Max file sizes and file restrictions in IBM Connections

As all the parts in IBM Connections are somehow developped on its own there is no
global configuration interface to set options like the maximum allowed file size and
what kind of files are allowed.

Every part has it own configuration and also its own way how to configure it.

For Blogs there is an administration interface to do this but for now this is
the only part which will give you a GUI to administer the application.

The other parts require you to either find your way through WebSphere wsadmin
commands or to edit XML files.

By browsing through the configuration XML files you will find that some parts are
simulair to eachother. The configuration and administration for Files and Wikis
feels like the same people were involved when it was developped.

Find below an overview of the different max. file sizes and the file restrictions per
IC component and where to edit them.
