	left = DRIVESPACE("c:\")
	println "There are ",tostring(left)," bytes on drive C."

`drivespec´ must include at least a drive letter AND a colon. Backslash is optional. With directory specs it will work also. valid drivespecs are C: C:\ C:\PCB These will all return drivespace left on dirve C
*NOTE On LANTASTIC this will return drivespace of the current physical drive even if it is mapped as a directory.
