I've just downloaded a 4.5GB depot to a location on my hard drive that is not ideal.
I'd like to move the folder that Perforce now sees as the "workspace" folder (iPhone) to another folder on my hard disk (Project Name), and then use that folder as the workspace folder.
Is this possible, or do I need to download the entire depot again?
in the P4V application:
Open the Workspace dialog: Go to Connection>Edit Current Workspace... change "Workspace root:" to where you like
If you have not already moved the files, P4V will offer to copy them for you.
