When you click Finish, the data you have entered in this wizard is saved. You return to the Mounted File Systems tab of the File Systems property sheet. The definition for the TFS file system that you have defined will be displayed on that panel.
msys builds a MOUNT statement for the TFS in the BPXPRMxx parmlib member.
If you specified a new mountpoint directory that does not currently exist, you must create the mountpoint yourself, outside of msys -- for example, you can do this with the mkdir shell command.
If you click Cancel, no data is saved. You return to the Mounted File Systems tab of the File Systems property sheet.
