What you need is the -openFile:, -openURL: or
-selectFile:inFileViewerRootedAtPath: methods of the NSWorkspace class.

Just to clarify that, think of the folder as if it was a file. The
application which opens folders is the Finder. So when you tell the
operating system to open a folder, it tells the Finder to open a
window showing its contents.

Here is some actual, tested, working, source code:

NSString* path = @"/Developer/Applications";
NSString* scriptString = [NSString stringWithFormat:
@"tell application \"Finder\" to open posix file \"%@\"", path];
NSAppleScript* script =
[[NSAppleScript alloc] initWithSource: scriptString];
NSDictionary* errorDict = nil;
[script executeAndReturnError: &errorDict];
[script release];

Obviously, in a real program:

You'd want to look at the autoreleased errorDict from
executeAndReturnError.

You'd need to process 'path' to escape any backslashes and double quote
characters in it.

The NSWorkspace answer mentioned earlier in this thread is faster and
better recommended.

You are quite right. Thanks for the correction.
