hi to every one,

 I am trying to aceess data from files and want to display them in one by one.

when i am debug my program i got an error that no such file exists,even iam storing it,

here is my code can any one help me to find out the problem

thanks in advance.

var myFile:File = File.applicationStorageDirectory.resolvePath("abc.txt");
		myFile.createDirectory();
		
			if(myFile.exists)
				Alert.showAlertDialog("File Found");//i got output as file not found
			else
				Alert.showAlertDialog("File Not Found");
			
	var fileStream:FileStream = new FileStream(); 
	fileStream.open(myFile, FileMode.READ);

var myFile:File = File.applicationStorageDirectory.resolvePath("abc.txt");
			
		if(myFile.exists)
			Alert.showAlertDialog("File Found");
		else
			Alert.showAlertDialog("File Not Found"); // this stmt is executing
			
			var fileStream:FileStream = new FileStream(); 
			fileStream.open(myFile, FileMode.READ);

that's because you try to create a directoy when a file is expected

either you should do this

var myFile:File = File.applicationStorageDirectory.resolvePath("abc.txt");
		var fs:FileStream;
		
			if(myFile.exists)
				//Alert.showAlertDialog("File Found");//i got output as file not found
                                trace("file found");
                        else {
				//Alert.showAlertDialog("File Not Found");
fs = new FileStream();
fs.open(myFile, FileMode.WRITE);
fs.close(); //now you have your file
}
			
	var fileStream:FileStream = new FileStream(); 
	fileStream.open(myFile, FileMode.READ);

 or, if you want to have a directory

var directory:File = File.applicationStorageDirectory.resolvePath("data/myDirectory/");
if (!directory.exists)
     directory.createDirectory();

var list:Array = directory.getDirectoryListing();
            for (var i:uint = 0; i < list.length; i++) {
                trace("File found: " + list[i].nativePath);
            }

actually i didnt use the creatredirectory() method, that was in comments block, so no effefct to code,

your code is similar to my code, there is no difference,

but the problem is my application cant get the local stored file, 

can any one pls tell me to where i need to store the my file.

If it is files that you dont want the user to have access to (e.g. preferences), then the app-storage directory is fine. If you want the user to have access to it and/or what the files to remain on the device if the app is removed, then the documents directory is where you want to place them. If you do put them in the documents directory, then you need to make certain you allow file access/permission in the bb app xml file.

you should look closer, there is the difference that i create the file if it doesn't exist. i open a filestream directly, store it and close it again so that the file exists

Hi Sir,

I am got the solution,

the problem is i am using ApplicationStorageDirectoy that was not accepting my file, applicationDirectory Is suitable for accesing the data.

Ah, so the file is installed with the app. Missed that part.
