How to combine Split files in Windows

Last weekend I did some cleanup of my Linux machine and transferred all files over to the Windows machine. I ran into problem to transfer bigger files than 4GB so I needed to split the files before transfer and put them back together in the windows machine.

To split a file in Linux to 100MB per piece write:
split –b 100m /path/to/large/file /path/to/output/file/prefix

To put them together again on windows write in the command prompt
copy /b /path/to/output/file/prefix* files.tgz /b
