To add a new or an existing file item to a project, select the context menu item 'Add'. The 'New File' dialog offers 3 different categories of files to add:
File templates from categories C# and VB provide different file types containing a skeleton for classes, interfaces or structures.
Resource or simple text based files are part of the 'Misc' folder.
In addition to Ranorex specific files, it is also possible to add documents or other file types to a Ranorex project. Add a user specific file by using the context menu item 'Add' | 'Existing Item...'.
