It is possible to override the default set of file types that the type checker should recognize as archivable resources.
To do so, place your custom filetypes.txt configuration file in the root of your local storage directory (to find out what that is, select Local Corpus Storage Directory from the Options menu). It will then automatically be installed in the type checker as soon as type checking takes place for the first time during a session. You will need to restart Arbil if it is already running.
For information about obtaining or creating a custom file types configuration, please contact your administrator.
