Microsoft Project Trivia: Options Settings – Where Are They Stored?


I answered in question recently in the Project Online General Questions and Answers user forum. The user asked a question was about the leveling options found in the Resource Leveling dialog and how to distribute those leveling options settings to other Microsoft Project users in his organization. I thought the question was interesting, and in response, I decided to share a bit of Microsoft Project trivia with you.

Many years ago I was teaching a Microsoft Project desktop class to a group of project schedulers in New Orleans, LA. I loved that class because my students had many years of experience working with Microsoft Project to manage projects in the petrochemical industry. During the class, a “know it all” student asked me where Microsoft Project stored the options found in the Project Options dialog. I told him that some of the options are project-specific and are stored in the active project. And I told him that application-specific options are stored in the Registry. He immediately exclaimed, “That’s wrong! Those options are stored in the Global.mpt file.”

I knew he was trying to “show me up” in front of his fellow schedulers, so I said, “No. They are stored in the Registry. Let me show you.” I changed a bunch of application options, such as the Date format option on the General page of the Project Options dialog shown in Figure 1, and then I exited Microsoft Project. I said to him, “So if I delete the Global.mpt file and restart Microsoft Project, would you agree that doing so should reset all of those options back to their default settings?” He said yes.

I launched my Windows Explorer application, navigated to the folder where Windows stores the Global.mpt file for Microsoft Project, and then I deleted the Global.mpt file. By the way, when you delete the Global.mpt file and then relaunch Microsoft Project, the software automatically creates a new Global.mpt file for you. When I launched Microsoft Project again and returned to the Project Options dialog, my options settings were exactly the way I left them, which proved that those options were not saved in the Global.mpt file. My “know it all” student was thoroughly embarrassed, especially when his fellow schedulers started ribbing him saying, “Dude, you just got busted!” After this little demonstration, I showed the class where the Windows system actually stores the application-specific options for Microsoft Project.


About the Registry

As I mentioned previously, Microsoft Project stores application-specific options in the Registry. You can find application-specific options in two different dialogs: in the Project Options dialog shown previously in Figure 1 and in the Resource Leveling dialog shown in Figure 2. To access the Resource Leveling dialog, by the way, click the Resource tab to display the Resource ribbon, and then click the Leveling Options button in the Level section of the Resource ribbon. In the Resource Leveling dialog, all of the options are application-specific except for the Leveling range option, which is project-specific.

The Registry is a database file used by the Windows system to manage the settings for both Windows and for all of the software applications installed on your computer. To view the Registry and its many settings, click the Start button, type regedit on your computer keyboard, and then press the Enter key to launch the Registry Editor application.

In the Registry Editor application, you can locate the application-specific options for your copy of Microsoft Project by navigating to the following folder:

HKEY_CURRENT_USER/Software/Microsoft/Office/16.0/MS Project/Options

Figure 3 shows the Options folder for Microsoft Project in the Registry Editor dialog. Notice that the Options folder contains a number of subfolders, such as the Calculation, Calendar, and Edit subfolders. Each of the subfolders maps to a specific area of either the Project Options dialog or the Resource Leveling dialog.

For example, the Leveling subfolder maps directly to the options found in the Resource Leveling dialog. If you select the Leveling subfolder, for example, the Registry Editor reveals the settings found in the Resource Leveling dialog, such as shown in Figure 4.

Figure 4: Registry settings in the Leveling subfolder


If you double-click one of the Registry settings on the right side of the page, the Registry Editor displays the Edit DWORD (32-bit) Value dialog with the current value for that setting. For example, Figure 5 shows the current value for the Leveling Period Basis option.

Figure 5: Leveling Period Basis value


The Leveling Period Basis option maps to the Look for overallocations on a _____ basis option at the top of the Resource Leveling dialog. In the Edit DWORD (32-bit) Value dialog for the Leveling Period Basis option, you can correlate the value displayed in the Value data field with the option setting in the Resource Leveling dialog as follows:



After all of this Microsoft Project trivia, are you still awake? If so, remember that Microsoft Project stores the application-specific options in the Registry and not in the Global.mpt file.

And speaking of the Global.mpt file, what exactly does Microsoft Project store in this file? To see the data stored in the Global.mpt file, click the File tab and then click Organizer button in the Organize Global Template section of the Info page in the Backstage. Figure 6 shows the Organizer dialog.

Notice in the lower left corner of the Organizer dialog that the Views available in field displays the Global.MPT value, which allows you to see all of the objects stored in the Global.mpt file. Always think of the Global.mpt file as your “library” of default and custom objects such as Views, Tables, Filters, and Groups in your copy of Microsoft Project The tabs across the top of the dialog show you exactly which objects are stored in the Global.mpt file. Notice that these objects include Views, Reports, Modules, Tables, Filters, Calendars, Maps, Fields, and Groups.

  1. As a power user (those people that use Project routinely), understanding the conceptual nuiences associated with Options and the Global.MPT file can really save a lot of time and make the experience of using Project richer.

  2. Thank you! That was a very informative piece of trivia.

    And yes, I had just finished a double espresso prior to reading the article, which means I will not go anywhere near regedit or my global.mpt until my fingers stop shaking.

  3. Oh, Robin, you are way too funny! And thank you for those very kind comments, my friend. 🙂
