The partition should be unmounted to undelete any files without further data loss. If the partition is not currently mounted, this message indicates it was improperly unmounted, and you should run fsck before continuing. If you decide to continue, extundelete may overwrite some of the deleted files and make recovering those files impossible. You should unmount the file system and check it with fsck before using extundelete. Would you like to continue? (y/n) y Loading filesystem metadata ... 192 groups loaded.

'path' is relative to the root directory of the file system. The restored directory is created in the output directory as 'path'. --restore-all Attempts to restore everything. -j journal Reads an external journal from the named file. -b blocknumber Uses the backup superblock at blocknumber when opening the file system. -B blocksize Uses blocksize as the block size when opening the file system.
