Your client workspace is the area on your local filesystem where you work on files managed by Perforce. Your Perforce client spec defines your workspace location, the depot files you plan to work with, and where they will be located in your workspace when you invoke Perforce commands.
You must create a client spec before you can do any work with files in your workspace. You can then use Perforce commands to move files to and from a shared file repository on the server (the depot). You can retrieve files from the depot into your own client workspace, where you can read, edit, and resubmit to the depot for other users to access.
Accessing Client Specs
Choose Go To->Client Workspaces to view a list of all client workspaces known to the Perforce server. Clicking on a client name in this lists takes you to the Client Detail page. If you select a client name that does not match current client workspace, you can make that your current client by clicking the "Switch to" link at the end of the page. For information about the attributes of a client spec, see Editing Client Specs.
