- Possible master files - The files presented on the first level in this category are not imported or included from other files. These files are most likely to be set as master files.
- Cycles - The files that are presented on the first level have circular dependencies between them. Any of the files presented on the first level of a cycle is a possible master file.
- Standalone - Files that do not include or import other files and are also not included or imported themselves. It is not necessary to set them as master files.
To set them as master files, simply enable their check-boxes. Oxygen XML Editor plugin marks all the children of a master file as modules. Modules are rendered in gray and their tool-tip presents a list of their master files. A module can be accessed from multiple master files.
The master files that are already defined in the project are automatically
            marked  in the tree and cannot be removed. The only way to disable a master file
            is to delete it from the Master Files folder.
         
The next panel displays a list with the selected master files. Click the
            Finish button to add the master files in the
            Master Files folder.
         
You can use the Select Master Files option to automatically mark all master files. This action sets all the resources from the Possible Master Files category and the first resource of each Cycle as master files .
