Does the phone support file browser instead of relying on third party apps??

Answer 1

Android does not have a native file browser, but there are numerous third-party ones (Astro comes to mind). The filesystem of Android is that of Linux; the path separator is / and the FS grows from a single root called /. So, you have your app packages under /data/apps, and so forth. Unless the phone is jailbroken ("rooted"), you won't get to see the whole filesystem - permissions get in the way. This applies to all Android applications, they are sandboxed - that is, they don't get access the whole filesystem. There are API calls to get the path to the current application's sandbox directory.
