What is a .wmv file?
A .wmv file is a windows Media video. Its registered MIME type is video/x-ms-wmv, which places it in the video family of formats.
Technically it is a specialised form of application/vnd.ms-asf (the .asf format), so tools that understand that format can often read at least part of it.
WMV is a binary format: the contents are not readable text, so opening it in a text editor shows scrambled characters.
