Where is the list of applications in this statement?

In the AppleScript Language Guide is says:

@ASLG

The choose application dialog initially presents a list of all applications registered with the system.
To choose an application not in that list, use the Browse button, which allows the user to choose an
application anywhere in the file system.

Where is that list of all applications registered with the system kept?

I guess in the LaunchServices Database, but I don’t know where it is on disk

Ahh – thank you. With that hint I found it in ~/Library/Preferences/com.apple.LaunchServices.plist

They’re a bunch Dictionary pairs of bundle IDs and application names, e.g.:

LSHandlerRoleAll = “com.red-sweater.marsedit”;
LSHandlerURLScheme = marsedit;

They correspond to the info this script give you:

tell application "System Events"
	set P_running to processes whose visible is true
	set tID to {}
	repeat with proc in P_running
		set end of tID to {name of proc, bundle identifier of proc, creator type of proc}
	end repeat
end tell
