Description
If I load a folder with zarr but there is no .zarray, it deletes my data! This is really not good and not obvious.
Is this intended or a bug?
I now know that the load function is not read only!
Instead use open_array with read only mode:
z = zarr.open_array(path, mode='r')Steps to reproduce
(env) /Users/Documents/test_folder/video_2025-04-22_16-47-43-917 $ ls
zarr_folders rgb
(env) /Users/Documents/test_folder $ python
