|Getting Started / Defining a Working Copy|
Check Out is the term used to describe the process of making a copy of a project from a repository into your local file system. This checked-out copy is called a working copy. A Subversion working copy is a specially formatted folder structure which contains additional .svn folders that store Subversion information, as well as a pristine copy of each item that is checked out.
The Check Out dialog is displayed:

By default the last (HEAD) revision is checked out. If you need another revision, you have to select the Revision radio button. To specify the revision number you can simply type the revision number in the corresponding text field or click on the History button which opens the History dialog.
