and then use a different instance of Windows Explorer to manage your files.
Going back to Task Lists returns My Computer to it's default, and since this is a "System" instance of Windows Explorer, it may be better not to change that.
But Windows Explorer is available elsewhere, for example Start > All programs > Accessories > Windows Explorer, and you can right click that to send a shortcut to the Desktop. That instance of Windows Explorer should open in the 2-pane view which will enable you to manage your files easier.
I'm a little confused. I am on my Windows 7 system at the moment and this does not have the "File Types" tab in Folder Options. I would have to wonder if changing the default actions in File Types was the best way to go. I was always a little apprehensive in amending anything there, and in fact in Vista and Win 7 Microsoft removed File Types altogether because of the problems sometimes caused by amending things here.
So, I would go back to square one and try again a different way. If you can get that file type reversed, see if that solves the issue. If it doesn't, then hit the "Restore defaults" in the Folder Options dialog.
Does that help?
I recently received a tip on how to change the default view in Windows Explorer so that the pane on the left shows the folders tree rather than the tasks list. I did this via "Tools" -> "Folder Options" -> "File Types" -> "Folder" -> "Advanced" and changed the default to "explore".
This seems to have worked OK, as when I go to My Computer etc it does indeed open in the view I wanted.
I also found once I had done it that if I double click a folder in Explorer now, it opens in a new window, which I don't want. This is despite the fact that in the "Folder Options", the selected option is still "Open each folder in the same window". I tried changing that option, changing it back, restoring defaults etc and it hasn't made any difference.
AND just to make things even more fun, at some point along the way things have changed further and now when I double click a folder it not only opens in a new window, it opens as a "Search"! I have no idea how this started happening, as the Folder Options don't even have Search as an option.
Any ideas how to get this sorted out? Or at least get back to where I started, I can live without the explorer showing folders by default if I have to!
