If you did not commit after deleting, you can restore the file by selecting "Revert to HEAD" in the Manage Branches window.
If you committed after deleting the file the process is more complicated. The process is to find the commit before the one where your file got deleted, and revert to that. Generally, to make this easier, it's best practice to commit often and note in the commit log whenever you delete or add a file.

In the window that pops up, find the revision where your file was deleted. Either the log messages or the "Modified Files" section should list what files are deleted in each revision.
Select the revision before the one where your file was deleted (in the above example that's revision 2). Then select "Revert". Your file is now available.
