Unfortunately there is not much that can be done with this zip file. It is corrupted. I was able to recover level.dat33 up to level.dat73 but there are parts from dat0 to dat32 missing and any gap will make this save file not recoverable.

oh :/ sad
.. i have a save from same world <the corrupted world> that was 2 - 3 weeks ago from the corrupted world its was <backup> its from level.dat0 to level.dat50
and its work <but its an old save> so can it be merged with the corrupted world to restore the level dat missing ?

Merging of level data chunks from different save files is not allowed, it will not give anything usable.
