On this page, choose the way to map the files and folders on your server with their local copies. These mappings are referred to as workspaces. You can either specify new mappings and have a new workspace generated or use mappings from an existing workspace.
Choose this option to have PhpStorm generate a workspace for you, with the folder mapping based on your choice of the local and remote paths.
In this text box, type the name of the workspace to be generated.
Choose this option to have the data downloaded according to the mappings from an existing workspace.
