"Open with" option on context menu

[chescogala]

I have been trying to find documentation on adding an "Open with" option to the context menu, but I can't seem to find anything on this, is it possible to do so with Shell? If so, would it also be possible to make it so that the "Open with" options all relate to the file extension of the file that's being opened?

Thank you

you can edit the item by adding a file extension filter with find= or where=

I would like it to be like the Windows option that displays a submenu with the available apps to open that file.

Something like this:

I would really like if there was an option already coded since I am not the best at coding.

Thank you

I've already tried (twice) to recreate the "Open with" menu with NS syntax, but without success - I manage to match the information which extension should be opened with which programs, but I can't get them to open the file always (80% of the time)

But there is a solution: by modifying the registry to create a second "Open with" menu that will not respect anything other than the extension. This method only works in Win 11 (I've never tried it on another OS version, but I'm 99% sure it won't work).

• Do you want it as a reg file to activate it once, or as an NS command to activate/deactivate (toggle) it?
• Do you want this menu also on folders too? background? drivers?
• Do you want me to edit it a bit with NS syntax?

• What would be the benefit of having it as a reg file, or having it as an NS command to activate? And how would that NS command work?
• Yes, I would like it to also be on folders, drivers, and anything else that the original context menu would use the "open with" option
• About the syntax, whatever works best in this case would be perfect

Thank you very much
