One question per thread, please.
It works okay here.
Does the New -> Text Document menu item work for you?
If not, does it work in Explorer?
[quote]2)In the 'Folder Options dialog' when i tried use 'Save -->For This Folder + Layouts & Folder Tabs' the folder, present in the other 'tab groups' are not update with the new format.
But should upgrade the format even if the folder is present in different tab groups?[/quote]
Even if you close & re-open the window or tabs?
Saving the format has no effect on open windows, only on saved settings.
