Besides being a solid general-purpose free compression app for Windows operating systems, 7-Zip is also available for several other like Debian, Ubuntu, Fedora Core, FreeBSD, Mac OS X and Solaris making of 7-Zip a real multiplatform. Today I’m going to tell you how to use 7-Zip program to break up a large file into several smaller files which is really useful for sending them via e-mail.

But before we go on, you need to know that the only indispensable thing to follow this tutorial is to have 7-Zip installed on your computer, so, to get it for free just click on the “Download” button above. The InstallIQ installer will take care of the setup process.

OK, let's say you have a 100 MB file or folder you need to send your colleague by e-mail but your e-mail server does not allow you to send files bigger than 10MB. What you have to do to solve this situation is to ask 7-Zip to compress the file, you can either browse to the file/folder and right click on it and from the contextual menu select 7-Zip → Add to archive...

Or you launch the 7-Zip File Manager and browse to the file/folder and go to File → 7-Zip → Add to archive...

In both cases you'll arrive to this dialog:

Here you can adjust several options and parameters but what matters most for this example is the “Split to volumes, bites” for 10MB parts type 10M. As you can see in the next screen capture there are various pre-made options like 650M for CD's, 4480M for DVD's and so on and so forth.

Once you are satisfied with your selections, click OK and the compression process will begin, a dialog showing a progress bar will show up.

At the end you'll find the parts in the folder you selected named as *.7z.001, *7z.002 and so on … The parts name varies depending on the file format you selected: for zip format it will be *.zip.001.
