# Recognized environment variables

When the XML files `MigDocs.xml`, `MigApp.xml`, and `MigUser.xml` are used, the environment variables can be used to identify folders that can be different on different computers. Constant special item ID list (CSIDL) values provide a way to identify folders that applications use frequently but could have different names or locations on any given computer. For example, the **Documents** folder could be `C:\Users\<Username>\Documents` on one computer and `C:\Users\<Username>\My Documents` on another. The asterisk (\*) wildcard character can be used in the `MigUser.xml`, `MigApp.xml` and `MigDoc.xml` files. However, the asterisk (\*) wildcard character can't be used in the `Config.xml` file.

## Variables that are processed for the operating system and in the context of each user
