The macOS API I wrapped in the extension should take all of the into
account.

Wow, way more complicated than I imagined.

From: 
https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFBundles/AboutBundles/AboutBundles.html

How the System Identifies Bundles and Packages
The Finder considers a directory to be a package if any of the following 
conditions are true:

• The directory has a known filename extension: .app, .bundle, 
.framework, .plugin, .kext, and so on. 
• The directory has an extension that some other application claims 
represents a package type; see Document Packages. 
• The directory has its package bit set.


So to translate:
We know it when we see it because we have a list of the ones we use.
The application that created it defined a package/bundle type in its 
Info.plist file. Did you search the plist files for all the applications that 
everyone has on their computers to find all the file types that are not 
folders? good luck
The folder / package has its package bit set (which doesn’t seem to be 
accessible with terminal commands as far as I can tell).


I’m exploring terminal commands to see if this mythical package bit can be 
detected for directories that appear to have a file type on them.

What a mess.

I’m pretty sure bundles always have a PkgInfo file in them too - so you should 
(alternatively to using LCB) use ‘there is a file ...’.

Warmest Regards,

Mark.

If you don't get any pure LCS solutions you could use an extension. macOS
has an API for this:

https://developer.apple.com/documentation/appkit/nsworkspace/1529991-isfilepackageatpath?language=objc

I just tested it in my macOS test bed for extensions and it seems to work.
It is the NSWorkspaceIsFilePackageAtPath() handler in this file:

identifying macOS folders that are considered to be files?

[kee nethery via use-livecode]

Is there any way for LiveCode to tell me that a macOS folder that gets listed 
with “the folders” is actually treated as a file? For example, .app is a file 
where View Package Contents is an option but the OS treats it as a single 
thing. Same with .numbers, .pages, and various other “files”. They can be 
opened up and the contents can be viewed.

Is there any way to know which “folders” are actually treated by the OS as 
files? 

Thanks,
Kee Nethery
