Titanium : How to find the Private Directory

gistfile1.js

	function privateDocumentsDirectory(){

		Ti.API.info('We need to open a file object to get our directory info');
		var testFile = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory);
		Ti.API.info('Now we remove the Documents folder reference');
		var privateDir = testFile.nativePath.replace('Documents/','');	
		Ti.API.info('This is our base App Directory =' + privateDir);
		Ti.API.info('Now we add the Private Documents Directory');
		privateDir+='Library/Private%20Documents/';
		Ti.API.info('Our new path is ' + privateDir);
		return privateDir;		
	};
	
	var myDbName = 'foo123';
	Ti.API.info('We create a db to test our method')	
	var testDb = Ti.Database.open(myDbName);
	var testNativePath = testDb.getFile().nativePath;
	Ti.API.info('Our nativePath to test against is ' + testNativePath + ' this is what we need to end up with');
	var privateDocFolder = privateDocumentsDirectory();
	Ti.API.info('Our Private Document Folde is ' + privateDocFolder);
	Ti.API.info("Let's see if we can find our database");
	var dbCheck =  Ti.Filesystem.getFile(privateDocFolder, myDbName+ '.sql');
	Ti.API.info('Did we find it? ' + dbCheck.exists());
	Ti.API.info('Do our file paths match? ' + (dbCheck.nativePath==testNativePath));
	Ti.API.info('Example Finished');

Wondering if this is still valid. Guess I need to find that out.
