If you have configured your project file to use a version control system, and have checked in your files in accordance with the procedures described in the VCS documentation, you will see one of the icons of Table 16.3 in the Checkout Status column of the Project window for every file under revision control in your project. Refer to Figure 16.6 to see where the Checkout Status column is located in the Project window.

Clicking the Checkout Status column icon at the top of the column will perform a Synchronize Status command on the project's files against the revision control database. The status of all files you have on your hard disk will be compared and synchronized with the status of the files in the revision control database.

In addition, the VCS Pop-up menu in the file's editor window will always indicate the current checkout status of the file.
