HI,
Where can i find the file extension <-> Application map.
If windows gets a file by the name abc.txt, where does it to find out that the default app to open is Notepad.exe.
Thanks, Appricaite the help

The majority of that information is stored in the [HKEY_CLASSES_ROOT] hive. For example, look-up the extension ".txt" at [HKEY_CLASSES_ROOT\.txt] which tells you that ".txt" should be treated as a "txtfile". So then open [HKEY_CLASSES_ROOT\txtfile] this key includes some sub-keys that define how that file type should be handled:

- [DefaultIcon] defines the icon
- [...\shell\open\command] specifies which command to use to open the file (e.g. notepad.exe)
- the [print] subkeys specify how the file should be printed if Print is selected from the right-click context menu.

Hope this helps you get started.

Regards,

Simon Clausen

Simon,
does this supercede what extensions are defined in INI if it is found in both?
