When a file has a name such as File.tar.lzma or File.tar.bz2, HTTrack changes
it and the new file name is File.tar.tar

So, when you want to download the MiKTeX package from one of the CTAN mirror
websites (because it's faster) all the archive names are corrupted.

For instance, you can see it with this link:
<ftp://ftp.oleane.net/pub/CTAN/systems/win32/miktex/tm/packages>


How can we solve it?
