Copy
Use Modify|Copy to create a copy of a file or directory which is already under SVN control. This command will preserve the history of the copied item.
Select the Target Directory under which the copy of the file/directory will be created, and specify the New Name.
There is also a special mode of this command that can be used to tell SmartSVN ‘after the fact’ that a file was copied. For this to work, exactly two files must be selected: One that is versioned, but not added or replaced, and another that is unversioned, added or replaced. SmartSVN will then add the unversioned file (if necessary) and connect the history of the added file to that of the other file.
Tip
You can also use Drag-And-Drop to copy or move files and directories.
