    if (tab.url.indexOf(\'https\') > -1) {
        var ta         


        

Answer 1

This filesystem API does not appear to actually write a true "file" to your hard disk. It seems to store a file within a sandboxed safe zone in the browser. You'll have to write a quick and dirty little file manager (or find one out there) to manage the files for a given web app. You can also try visiting filesystem://<your URL here>/temporary/ to see all the files that your app has created.

Answer 2

Based on this:

At the time of writing this article, Google Chrome 9+ has the only working implementation of the FileSystem API. Since a dedicated browser UI does not yet exist for file/quota management, the API cannot be used without running Chrome with the --unlimited-quota-for-files flag (Note: if you're building an app or extension for the Chrome Web Store, the unlimitedStorage manifest file permission will suffice).

I assume you are using Chrome and that you have not set the --unlimited-quota-for-files flag

Answer 3

What about just using localStorage?
