Trying to get all files opened to be in the same instance

[Bob Barringer]

My computer opens a new Notepad++ instance every time I open a file. How can I get them to all just be tabs in the same instance?

settings > preferences > multi-instance ☑ Default (mono-instance)

Also, if that isn’t sufficient, make sure that your shortcuts and registry entries don’t add the -multiInst command line option.
