        You can use the ClearTeam Navigator or ClearTeam Details view to delete resources under ClearCase® source control. On Windows systems, you can also perform this operation from Windows Explorer. The resources are not, in fact, deleted: they are only uncataloged from the current version of the directory and can be recovered from the predecessor version of the directory.
        Moving resources
        You can use the ClearTeam Navigator or ClearCase® Details view to move resources under ClearCase source control. On Windows systems, you can also perform this operation from Windows Explorer. This operation affects resources (versions) in the local ClearCase view and elements in the VOB.

Hijacking files

Hijack a file when you need to modify it when you cannot connect to a server.

Procedure

Note: You can hijack files only in a Web view, automatic view, or snapshot view. You cannot modify a version in a Dynamic view until you check it out.

To hijack one or more files:

Select the files that you want to hijack.
Use the ClearTeam Details view, ClearCase® Search Results view, or the ClearCase® Version Tree view. If you are working in the Eclipse environment, use any Eclipse view that supports the Team context menu.
To open the Hijack dialog box, click the icon on the ClearCase® toolbar, or take one of the following actions:
- Select Hijack from the context menu in the ClearTeam Details view.
- In the Eclipse environment, select Hijack from the Team context menu.
- In the ClearCase® Version Tree view, right-click the version selected by your view and click Hijack.
Click OK.

Results

The selected files are marked as hijacked and become modifiable. If resource decorations have been enabled, hijacked files are decorated with the icon.
