With Modify|Copy From Repository you can copy a file or directory from the repository to your local working copy. This command is useful to resurrect dead files or directories from earlier revisions.
Repository is the repository of your local working copy, it can't be changed as copies can only be performed within the same repository. For Copy enter the file/directory and its Source Revision which shall be copied. Specify the local directory Into Local into which the file/directory shall be copied. With Name will be the actual name (last component of the path).
