Gus,
Here are my registry settings for .dat. Compare to yours and see what
differences there might be.

is interesting. Depends on how the key gets exported.
Shows this one way
%SystemRoot%\system32\NOTEPAD.EXE %1
and has that long hex value another way.

Gus,
"Click on Restore." from my previous post meant...
Click the Restore button to restore the defaults. I did not mean
System Restore.
The Restore button is there for .dat files because you or a program
changed something.

Thank you Wesley Vogel,
unfortunatelly I disabled restore since I had problems after
installing and uninstalling Nero which I believe caused this
alteration, in the first place.
The problem is that the DAT extension should open with Notepad and it
does but then there is the following : You have customized files with
extension 'DAT'. To restore these files to their default type(Video
CD),click Restore.
I really don't know what I did but somehow I replaced the "Advanced"
button with "Restore" on the tab File Types and changed the File
settings as well.
"DAT File" is the only Registered file type with a "Restore" button
instead of an "Advanced" one and with it's settings changed (instead
of Type: DAT File it says Video CD)
Have I outlined the problem correctly, can you provide any leads on
how to repair this ?
:
Click on Restore.
Restore resets the selected extension to the previous file type.

I have a problem in the Win Explorer---> Tools ----> Folder Options.
In the tab File Types, Registered file types: have 4 buttons ,
"New", "Delete" , "Change" and "Advanced".
This Extension= ".DAT", File Type= "DAT File" has no "Advanced"
button but a "Restore" one.
How can I fix this?
