[Geany] To open recursively a folder?

[Retourné du Japon]

Hello,

one simple question : is there a way to open recursively all the files
contained in a folder?
I work on a quite large project (about 100 php & css files), use the
built-in project manager of geany, but would like to be able to say
«open all the files in that folder», in order to clean / be sure I’m
actually working on *all* the files hosted online.

I hope te be clear, thanks for your attention,
Clément.
