Hi,

I would like to associate files with no extension with notepad++ I created a new system file type with no extension using the dopus file types gui. It seems to work perfectly in Windows explorer, but dopus still brings up the 'choose program' dialog even though the notepad++ icon is correctly associated with these files.

Any ideas? Thanks!
