About the Revit.ini File for Installation

The Revit.ini file contains settings that define variables, paths, recent files, and other settings for the Revit software.

Many settings do not appear in Revit.ini until their default values change. For other settings, you can add them to Revit.ini to cause certain behaviors.

Important: Always make a backup copy of Revit.ini before making any modifications. This strategy allows you to return to the backup copy if the changes result in unintended behaviors.

Revit uses 2 versions of the Revit.ini file:

Edit Revit.ini when you want to change settings and...	Folder name	Location
you have not yet started Revit for the first time	UserDataCache folder	C:\ProgramData\Autodesk\<product and release>\UserDataCache
you have already started and exited Revit	User Profile folder	C:\Users\<username>\AppData\Roaming\Autodesk\Revit\<product name and release>

The UserDataCache folder contains default copies of files that are used to populate the user's profile, including Revit.ini. When Revit starts for the first time for a new user, it receives a copy of Revit.ini from the UserDataCache folder. Thereafter, Revit uses information from the User Profile version of the Revit.ini file.
