If you are using a file manager like Total Commander on Windows, simply create a new text file (Shift+F4), name it like you want followed by `.uue` extension
i.e. `hypervisor_for_rootkit.tar.gz.uue`

Then paste the whole encoded symbols in that new text file with `*.uue` extension including the `'begin ...'` and `'end'` strings.

Now open (click) that file in Total Commander and it'll be ready to unpack (decode) it to the sidebar location.
