filetypes.conf has immediate effect and can be per repository
As a developer, I can specify what is the type (text/binary) of file with a given extension. But, I want PlasticSCM to immediately apply these settings to the current workspace (only new files are affected). Also, it would be convenient that a filetypes.conf placed in the root dir of repository to have the same effect for this specific repo, on the top of global settings (as for ignore.conf).
As your company grows and you start having more developers use Plastic, it gets a little frustrating making sure everyone has a "filetypes.conf" that is synchronized with everybody else's. There are a lot of file types out there are plain text but cannot be merged. Please ensure there is a repository level "filetypes.conf".
