File association quirks

[Terry Pinnell]

I frequently discover odd quirks concerning file associations. Here's
one example.

If I enter
ASSOC.avi
at a Command prompt, I get the result
..avi=NeroShowTime.Files

Yet I have AVI files associated with VirtualDub. And, for all AVI
files, the Type column in Windows XP Home folders shows 'VirtualDub'.

FWIW, in Folder Options>File Types, I see:
Details for 'AVI' extension
Opens with: VirtualDub
You have customized files with extension 'AVI'. To restore these
files to their default type (VirtualDub), click Restore.

For a long time the Type column *did* oddly show 'NeroShowTime',
despite d-clicking opening the AVI in VirtualDub. Can't remember what
I did to change that, months ago. But from the above evidence, it's
clearly still a bit dodgy behind the scenes. Anyone have any insights
please? Some obscure registry ambiguity or redundant entry?

Thanks, duly installed.
