When you install Revit on a computer, some important files reside in the UserDataCache folder, which is located here:
C:\ProgramData\Autodesk\<product and release>\UserDataCache
That folder contains the following important files, which provide default settings for each user:
- MaterialUIConfig.xml
- OmniClassTaxonomy.txt
- Revit.ini
- shxfontmap.txt
When you start the Revit software for the first time, your roaming user profile folder is created in the following location:
C:\Users\<username>\AppData\Roaming\Autodesk\Revit\<product and release>
The files in UserDataCache are copied to your user profile folder. As you use Revit, the software refers to the information stored in your user profile files, not to the files in UserDataCache.
Note: If you put a copy of Keyboardshortcuts.xml in the UserDataCache folder, those custom keyboard shortcuts are also copied to the user profile folder when you first start the software.
What does this mean?
- If you have not yet started Revit on the computer for the first time, you can customize the files in UserDataCache (such as Revit.ini). When you start Revit, those customized versions of the files are copied to your user profile folder and accessed when you use the software.
- If you have already started Revit on the computer and you want to customize any of these files, you must modify the files stored in your user profile folder. Changes to the files in UserDataCache do not affect your software.
