Usage

Overview

dump.f2fs is used to retrieve f2fs metadata (usually in a disk partition). device is the special file corresponding to the device (e.g. /dev/sdXX).

Currently, it can retrieve 1) a file or folder given its inode number (folders are dumped recursively), 2) NAT entries into a file, 3) SIT entries into a file, 4) SSA entries into a file, 5) reverse information from the given block address.

The exit code returned by dump.f2fs is 0 on success and -1 on failure.
