Activates the selected file in your workspace, adding it to the workspace’s default group. Doing so ensures that:

• The file is not read-only.
• The file won’t be overwritten by an Update command.

If your workspace uses the exclusive file locking or anchor-required feature, its files are initially read-only. In that case, you can Anchor the file before editing it, or AccuRev Plug-In for Visual Studio PE will invoke Anchor automatically when you save the file.
