Joining split files through the OS a classic command example of command line flexibility

If you frequently download large files in many parts then you are probably not a stranger to HJSplit. This application is used to connect these parts back together and is quite frankly completely unnecessary! So how do you do it?

Lets say you have just downloaded the following files:-


To join these into one big one:-


copy /b big_file_part.iso.00? big_file_part.iso


cat big_file_part.iso.00? > big_file_part.iso

Note the /b switch in the Windows command – this is important because it forces a binary copy. Its so simple why bother with that third party app šŸ™‚
