    Hi,

    as far as I know there is not any API for that. Anyway - files are not physically deleted and rewrited when you remove them, so they are probably still there, but to access them public SDK is not enough. Same for data stored in databases - they might be there - marked as deleted, but not physically removed from the db-file.

    Hi,
    there is a class RRawDisk which enables direct access to disk. if data remains on the disk physically, can we use this class to erecover it??

    Theoretically yes, however you will need to know the file system, which is not necessarily trivial (e: probably uses some variant of FAT, however c: uses some exotic file system - "logging flash fs"? - as I know).

    Hi stenlik,
    by private SDK, you mean to say nokia private SDK or symbian SDK.

    Hi,

    I mean that using the public SDK there are not tools for that, except theoretical use of the RRawDisk. This this not exclude the possibility that the Nokia/Symbian has some way how to do that as they develop drivers and they now better then us how the underlying stuff is working.
