I'm trying to download this website:
<http://banjr.com/lessons_ft.htm>

The .tef (virtual banjo tab) files are not being downloaded properly. In the
folder, the .tef file extensions have been changed to .html files.

This is an example error:
01:03:19 Warning:  File not parsed, looks like binary: banjr.com/tunings/C
Tuning.tef

I am trying to make it download correctly as a .tef file, not as .html. I am
not experienced in advanced computing at all, but any help would be
appreciated.
