Hi,
Sorry if this is off topic, but I am stuck.
What forums or mailing lists are suitable for
advice on the content of a particular video file?
The file (actually a set of eight files) has the
extension ".wmv", but Windows Media Player
gave the error that the file format did not match
the extension. VLC also will not play the file.
If anybody wants to look inside, I have placed
the file at:
https://sites.google.com/site/mytemporarydownloads/
Just scroll down to the "Video file" section.
The file was created by a fifteen-year-old boy
who passed away seven years ago. His
relatives are hoping the file contains video of
him.
Many thanks for any advice you can give.

GSpot doesn't recognize it.

The file existed as early as "2017-09-14 17:17:11 UTC".
It could have been uploaded for AV scanning on that date.
If you need a SHA checksum, it will be on that
page somewhere.

Um, a pretty confused sort of detection ???
We're going to need a hex editor for this. OMG.

And that means if VLC is asked to play it, chances are
it will refuse as well.

You can get a hex editor here. Install and load that file.
What do you see ? LOLZ. I think you'll see the problem
when you do this. HxD for the win.

Here is a picture of the screen, while I HxD it.

"sum" is an ancient program which adds all the bytes
together. Since all the bytes in the file are 0x00,
the sum of them is also "00000". The "sum" method is
rife with collision problems, and this is hardly a
good test to run, but it's something you'd do for a
very large file, where you suspected there might have
been at least one byte which wasn't zero. So this
tells me the file is zero all the way through.
sum Jack_Morrisson.11.wmv

If I selected the wrong file, please report back.
And don't waste someones time on a "video forum" with this :-)
HxD for the win.
