Many thanks for the example. I've tried it in the simulator and the courier, but it doesn't work (i'm working on a android 2.3.4 device). It fails with the message "File system is not accessible", either in read and write. Is there anything I can do?

1. what exactly does this function do

app.fileSystem.root.getFile("test.txt", { create: true }, GetFileEntryWriter, FileSystemFail);

2. and when you are calling the GetFileEntryWriter function you aren't passing any parameters, when it is expecting the fileEntry argument. So wouldn't that make the fileEntry.createWriter(WriteFile, FileSystemFail) function not work, as it would say cannot get method of undefined field fileEntry.

3. Why separate some javascript functions into the app.html page and the others into the index.js page? 

Thanks for the help Added By: User name 5 at: 2/10/2016 1:58:41 PM    4. Plus how do I access the functions in the app.html page from the index.js page, if it is possible 

Thanks again Added By: Nikolai (DevExpress Support) at: 2/11/2016 1:00:50 AM    Hi,

Here are my comments:
1, 2, This is the File plugin API. The decription of this plugin can be found here.
3. This is just an example. There is no specific reason for declaring functions in app.html file. The main requirement is that file syste should be initialized when device is ready. This inquiry is better related to basic PhoneGap concepts rather that to DevExtreme. I suggest that you refer to the PhoneGap Documentation to learn more.
4. If you wish to access functions an any part of your code, declare them in the global context as it is done for the gotFS function.

Make sure that you are testing the project on a mobile device, not in the DevExtreme simulator.
