This is an example for writing an image file (provided that you have its byte array imgdata available in memory):

FileConnection w=(FileConnection) Connector.open("file:///E:/Testapp1/",Connector.READ_WRITE);		
//Creates the folder	
w.mkdir();
w.close();
			
FileConnection wf=(FileConnection) Connector.open("file:///E:/Testapp1/image1.jpg",Connector.READ_WRITE);
			if(!wf.exists())
			{
				//Creates the file
                                                                wf.create();
				System.out.println("Created!");
			}
			else
			{
				System.out.println("Already exists!");
			}
			OutputStream fos=wf.openOutputStream();
			fos.write(imgdata);
			fos.flush();
			fos.close();
			wf.close();

Did you mean that you want to create a folder that only can be accessed by your application and not be other applications?

Try removing localhost i.e. ("file:///E:/abc");

Nothing like that,I just want to create folder from my application where I can save my files which will be accessible to user.

			fos.flush();
			fos.close();
			wf.close();

I don't want to write an image file,instead I want create folder for that image file.In your ex. its "Testapp1".

The first three lines create the folder. You might also need the following lines, that show how to save a binary file inside the folder, that you have just created.
