Commit Modified Files to Source Control
Before you commit modified files, review changes and mark any new files for addition
into source control. The files under source control that you can commit to a repository
display the Added to Source Control symbol 
or the Modified File symbol
in the Current Folder browser.
Right-click in the Current Folder browser and select Source Control > View and Commit Changes. In the View and Commit Changes dialog box, select the files to commit to the repository.
Enter comments in the dialog box, and click Commit.
A message appears if you cannot commit because the repository has moved ahead. Before you can commit the file, you must update the revision up to the current HEAD revision.
If you are using SVN source control, right-click in the Current Folder browser. Select Source Control > Update All from SVN.
If you are using Git™ source control, right-click in the Current Folder browser. Select Source Control > Pull.
Resolve any conflicts before you commit.
