How to handle large files by splitting them into smaller zip-files

When you zip a large file, a nice side-effect is that you can "span” it across multiple “volumes”. I remember first using this when restricted to 360kB floppy disks. Today it could be useful for getting around the 50000kB restriction (not sure about the exact limit?) in MS-Skydrive. Tempora mutantur

Unfortunately, Windows XP’s built-in ZIP-support does not cover spanned media. However, a good zip-utility which does, 7-zip, is free. Once downloaded and installed (can’t install? try http://media-convert.com for splitting, but it does not reassemble), you can right-click on a large file, e.g. this video below, and from the context menu choose 7-zip / “Add to archive", like so:

In the upcoming dialogue, enter in “Split to volumes” the size you want, then press “OK”:

7zip will automatically generate as many files as needed out of your big source file – remember that for unpacking you also need a zip program which supports spanned media.

Let’s enjoy ourselves and not worry about details like KB-MB conversion and that you could turn compression off to speed things up if you use 7-zip this way…
