macOS Associate file type (extension) with my app

[albebaubles]

I have an app that creates files with it's own extension type '.qaz'.

How do I go about programatically associating that extension with my application such that when a user clicks on the .qaz file my application automatically opens.

FYI, the app is Leopard and SL only.

Thanks.

Lookup universal type identifier in the documentation.

I believe this is done from info.plist

OK, the plist is what I've been trying, so I'm at least headed down the right path. My problem is the text editor still continues to open when I double-click my file.

Found it:

"Launch Manager" is responsible for opening files based on associations. Launch Manager settings are held in ~/Library/Preferences/com.apple.LaunchServices.plist. Some associations are cached in /Library/Caches/com.apple.LaunchServices*.csstore (the exact name varies with OS version). To remove the offending association:
rename/move the cache(s) (you could delete, but a rename/move is safer)
restart
open the LaunchServices preferences in the Property List Editor
search for and remove the association for the binary files.



I'm styling. Thanks, all.
