|Getting Started / Defining a Working Copy|
Check Out means making a copy of a project from a repository into your local file system. This copy is called a working copy. An Apache SubversionTM working copy is a specially formatted directory structure which contains additional .svn directories that store Subversion information, as well as a pristine copy of each item that is checked out.
The Check Out dialog box is displayed:

By default the last (HEAD) revision is checked out. If you need another revision, you have to specify the revision number or click the History button which opens the History dialog.
