I have a desktop app. This app has two panes. First pane shows view of the registry (as seen in regedit.exe). Second pane shows local filesystem view. Users can drag a registry or file into another side pane for some processing.
I want to convert this desktop app in to webapp that will run inside the browser. The question is how can I provide users with similar functionality of drag n drop registry and file in browser? For dropping files I can use HTML5 but how to do it with registry values.
As I understand I cannot access local filesystem from inside the browser hence what alternatives do I have? Expected end result is a way so that user can drag and drop a registry (from regedit.exe) or file from local machine into the browser. Also, I think HTML5 is not widely supported so any pointers on any other technology will also be appreciated.
Thanks.
