Merge 3 ISO file segments into 1 complete ISO file

Question

I need to merge 3 ISO files from Dell website and they state the following:

Download all ISO file segments into an empty subdirectory on your local hard drive. After you have downloaded all the file segments, run the following command to create the ISO file:

copy /b om* om650_suu_dvrpck_a00.iso [Windows]

I have created an empty directory on C: called b and dumped the ISO's into that directory, opened up CMD and tried the above; however, I get the following message:

The system cannot find the file specified.
0 file(s) copied.

Can anyone help?

Solution

Make sure you are in the correct directory in the command prompt when you are running the copy command. "/b" is not referring to a directory to place the files in, but a command-line switch to tell copy that it's appending a binary file.

i.e. when you open the command prompt the first command you run should be cd c:\b to place yourself into the folder named "b" indicated in your question. then run the command from Dell
