Use Windows Copy To Combine Split Files On Windows 7

Last night I was working on upgrading the BIOS on an older Dell Poweredge 650 that I have been using as a PostgreSQL development server. One of the CD’s I needed to create is downloaded from Dell as two parts of an ISO file that needed to be combined so below is information on how to combine the files using the Windows copy command.

List Of Files To Combine Using Windows Copy:


  1. C:\Users\alex\Desktop>ls -alh | grep om_
  2. -rwx------+ 1 Administrators None   1.5G 2010-09-16 10:57 om_5.5.2_suu_a00.iso.001
  3. -rwx------+ 1 Administrators None   1.4G 2010-09-16 10:42 om_5.5.2_suu_a00.iso.002

The above output shows the two files that need to be combined into a single ISO. This can be done using the copy command on Windows as shown below. In the below command we use /b to specify the output is binary instead of ascii which you would use /a to specify.

Combine ISO Split Files Using Windows Copy:


  1. C:\Users\alex\Desktop>copy /b OM* OM_610_SUU_A00.iso
  2. OM_5.5.0_SBUU_A00.ISO
  3. om_5.5.2_suu_a00.iso.001
  4. om_5.5.2_suu_a00.iso.002
  5.         1 file(s) copied.
  6. C:\Users\alex\Desktop>

In the above example of using the copy command the end result is a single ISO file that can now be burned to DVD. The copy command can be used to combine many sorts of files for example if you had two text files that you wanted to combine you could do that and the contents would be in the order of the files.
