To add elements (files and directories) to source control from Rational ClearCase Explorer or Windows Explorer (Windows)

In Rational® ClearCase® Explorer or Windows Explorer, move the files or folders to the VOB directory that will serve as the parent directory.
Select the items to add to source control. Then right-click.
You should select items that are the farthest from the root of the directory tree; the Add to Source Control command for a file or directory also adds any parent directories (up to the VOB root directory) that are not already elements.
On the Rational ClearCase pop-up menu, click Add to Source Control.
To add files and directories to a UCM project, in the Add to Source Control window, select or create an activity.
In the Comment field, describe the files or directories that you are adding to source control.
To continue working on the new elements after you add them to source control, select the Checkout after adding to source control check box. To leave them checked in, clear this check box.
If you are working in a replicated VOB (Rational ClearCase MultiSite®) and you are not using a UCM view, you can make your current replica master any branches created during the Add to Source Control operation by selecting Make current replica the master of all newly created branches. After the element is created, you can create new versions of the element on any of the new branches.
If you do not select this option, mastership of the main branch of the element is assigned to the replica that masters the main branch type. If the master replica is not your current replica, you cannot create any new versions on the branch. Also, if your config spec contains auto-make-branch rules, creation of the branches fails if the branch types are not mastered by your current replica.
Complete the operation by performing the following tasks:
- To add only one file to source control, click OK.
- To apply the comment and Checkout after adding to source control selection to multiple files, click Apply to All.
- To leave this item and any remaining items view-private, click Cancel.
  Tip: Before you add an element to a VOB, its parent directory must be checked out to your view. If the parent directory is not currently checked out, it is checked out before the element is created and checked in after the element is created.
