    When you open the case study and receive the file-not-found screen, edit the address to remove the characters after ".pdf" and the file will then open fine.

    As far as I know, Global Mapper does not select layers/files by file type, although that is an interesting idea.  

    There are several methods that you may find useful for organizing your files, whether within Global Mapper, or within several instances of Global Mapper, or by using other programs.  

    Within Global Mapper, you need to be able to select (highlight, not just make the files visible) the layers/files that will be assigned to a group.  When all of your files are loaded, then normal selection methods are useful (I'm using v18, so the methods may differ with the earlier OCC design).  Select all loaded files by using ctrl-A (possibly needing to click on one file then use ctrl-A).  Or, click on one file, then shift-click on another and the two files and all files in between are selected.  Or, ctrl-click on individual files.  Then you can right-click and define the group.  

    If your files have not yet been loaded, you can group your files into sets (by the names of files or by folders).  Load a set of files, select them, define a group, then save a workspace file.  The workspace file is plain text, so you can see the LAYER_GROUP definition for each file.  

    I will frequently open a separate instance of Global Mapper to organize and/or configure groups of files.  The results can be saved by exporting a single file for later use with different projects.  Or, the results can be saved as a workspace file from which file settings can be copied to a project workspace file and then loaded into GM.  

    You could use a text editor to create an entry for each of your files and groups.  The workspace file is a script, so opening the workspace file in Global Mapper will load all of the files.  

    You may be able to construct a separate script file for each group, with a program loop that will load all the appropriate files.  Again, use a workspace file as a guide to creating the structure of script files.  

    I have not played with Map Catalogs.  This structure may be useful, perhaps one per group.  The files are defined within the group, but are not loaded until the bounds of your current display require them to be loaded.
