In order to increase performance, ReiserFS is able to store files inside the b*tree leaf nodes themselves, rather than storing the data somewhere else on the disk and pointing to it. ReiserFS includes some special optimizations centered around tails, a name for files and end portions of files that are smaller than a filesystem block. PhotoRec ignores the file system this way it works even if the file system is severely damaged.
