To gain full access to the phone filesystem, you need special software to get around the limitations imposed by the phone UI. For Series 60 devices, the freeware FExplorer, written by Dominique Hugo, does that for you. You can download the latest version of FExplorer, or make a donation to support its development, at http://www.gosymbian.com/. Alternatively, a commercial product called Extended File Manager, from Psiloc (http://www.psiloc.com/index.html?id=159), has similar functionality.
The filesystem naming conventions that the Symbian OS uses are similar to those in the Windows OS. The C: drive letter is for the storage space for the system-level files in the phone's internal flash memory; D: is the RAM disk that stores runtime information; E: is the MMC card, storing applications and media files; and Z: is the Read-Only Memory (ROM) for the device's system software. The FExplorer program lets you create, delete, and manipulate directories and files in the filesystem. It also allows you to send any file to remote devices via Bluetooth, IR, MMS, or email. Now, let's explore some common files on a Nokia Series 60 smartphone.
What about Series 40 devices, you ask? Series 40 devices use the closed Nokia OS. Hence, only native applications developed by Nokia can have direct access to the filesystem. Nokia has not released any such application. In the future, the Java runtime on Series 40 devices might support the J2ME File Connection extension API, which would support file access from third-party Java applications. But for now, there is no reliable way for you to access the underlying filesystem on Nokia Series 40 devices.
