The EXPAND.EXE utilities that come with Microsoft Windows and the MS-DOS are not interchangeable. For example, if you try to expand compressed MS-DOS 6.x or Windows 3.1 file using the EXPAND command from MS-DOS 5.0 you receive the following error message:
Input file <filename> already in expanded format.
If a problem occurs when expanding files from the Windows or MS-DOS disks, use the respective EXPAND.EXE file that came with the product.
