Determining the source-control status of a file can be an expensive operation. CrossWorks will do this when:

• A file node is selected by the Project Explorer.
• The source-control status is displayed in the Project Explorer and the file node is visible there, too.
• Before a recursive source-control operation.
• After a source-control operation.

A file will be in one of the following states:

• Controlled:  The file is in source control.
• Not Controlled:  The file is not in source control.
• Checked Out:  The file is checked out.
• Old:  The file is older than the most-recent version in source control.
• Checked Out and Old:  Both of the above.

If the file has been modified, its status is displayed in red in the Project Explorer. Note that, if a file is not under the local root, it will not have a source-control status.

You can reset any stored source-control file status by choosing Project > Source Control > Refresh Status.
