Combine Split Files in Windows
I recently ran into an issue where I had about 7.5 GB of files split into 512M chunks downloaded from linux machine. The files had been generated using the split command:
split -b 512m files.tgz
This created the following files:
-rw-rw-rw- 1 user group 536870912 Mar 9 20:44 xaa
-rw-rw-rw- 1 user group 536870912 Mar 9 20:46 xab
-rw-rw-rw- 1 user group 536870912 Mar 9 20:49 xac
-rw-rw-rw- 1 user group 536870912 Mar 9 20:51 xad
-rw-rw-rw- 1 user group 536870912 Mar 9 20:53 xae
-rw-rw-rw- 1 user group 536870912 Mar 9 20:55 xaf
-rw-rw-rw- 1 user group 536870912 Mar 9 20:57 xag
-rw-rw-rw- 1 user group 536870912 Mar 9 20:59 xah
-rw-rw-rw- 1 user group 536870912 Mar 9 21:01 xai
-rw-rw-rw- 1 user group 536870912 Mar 9 21:03 xaj
-rw-rw-rw- 1 user group 536870912 Mar 9 21:05 xak
-rw-rw-rw- 1 user group 536870912 Mar 9 21:07 xal
-rw-rw-rw- 1 user group 536870912 Mar 9 21:09 xam
-rw-rw-rw- 1 user group 536870912 Mar 9 21:12 xan
-rw-rw-rw- 1 user group 222082405 Mar 9 21:13 xao
I wanted to combine them in windows and looked around for a while until I realized you can use Microsoft’s copy utility in binary mode!
copy /b xa* files.tgz /b
Now I’m all done! Hurray for built-in utilities.

Why do you need the /b flag twice?

Binary in, binary out.
