Contributor: SWAG SUPPORT TEAM { When dealing with multiple drives, it is helpful to know whether a drive is associated with a is attached to a letter (A, B, C, etc), and what its type is. This code uses the API GetDriveType function to do that. } function ShowDriveType(DriveLetter: char): string; var i: word; begin if DriveLetter in ['A'..'Z'] then {Make it lower case.} DriveLetter := chr(ord(DriveLetter) + $20); i := GetDriveType(ord(DriveLetter) - ord('a')); case i of DRIVE_REMOVABLE: result := 'floppy'; DRIVE_FIXED: result := 'hard disk'; DRIVE_REMOTE: result := 'network drive'; else result := 'does not exist'; end; end;
