Leslie Vail’s Dex.ini Switches Blog Article
At my recent Dexterity Training in Nashville, TN at Community Summit 2026, my students and I were discussing the Dex.ini “defaults” file used by Microsoft Dynamics GP and I was asked about the Dex.ini settings or switches and what they mean.
The Microsoft Dynamics GP Community’s “go to” for understanding Dex.ini settings has always been the resources created by my great friend, Leslie Vail.
Even though Leslie has retired from working in the Microsoft Dynamics GP world, her legacy continues with her book on development and her Dynamics Confessions blog.
Here are a few photos from the last Community Summit conference that Leslie attended (before her retirement) in Orlando, FL in October 2019.

There is no definitive list of Dex.ini settings as any Dexterity developer can create new settings as needed. These settings can be used to control behavior of code, such as enabling or disabling functionality or restoring previous behavior, or to temporarily store settings for the current workstation. So, while it will never be possible to identify and track every Dex.ini setting ever used, Leslie made a good attempt at documenting every setting she came across.
Here is the link to Leslie’s article with the Dex.ini Settings she documented.
Just in case the blog article is removed at any time in the future, here is a downloaded PDF as a backup.
Hope you find this information from Leslie, the Legend and my friend, useful.

PS: Leslie did visit with the GP Community during the Community Summit event in Charlotte, NC in 2023.
PPS: I bought Leslie one of the same Aussie Hats as she liked mine so much. Check out the Barmah Hat’s Kangaroo Leather Squashy Hat-In-A-Bag range (also available on Amazon).
