Predefined System Environment Variables

A file destination path specified in Target Designer or Component Designer must be defined as it is intended for the target system. To assist with this, environment variables can be used to represent folders on your run-time image. The list of environment variables provided in the Windows Embedded Studio tools displays each variable with its corresponding path on the development**system, not the target system, and the two are not necessarily the same.

The following table shows the environment variables listed in Target Designer and Component Designer and the resulting path on the target system.
