Problem/Question/Abstract:

How to tell what kind of drive is used

Answer:

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;
