MS-DOS 5.0 and Windows Expand Utilities Not Interchangeable

Q74251



The information in this article applies to:


  • Microsoft Windows versions 3.0, 3.0a, 3.1, 3.11
  • Microsoft Windows for Workgroups versions 3.1, 3.11
  • Microsoft MS-DOS operating system versions 5.0, 5.0a, 6.0, 6.2, 6.21, 6.22



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.

Additional query words: 3.10 3.00 3.00a 3.11 DOS 5.00 5.00a 6.00 6.20
