Abstract: The present application discloses a magnetic disk management method, an apparatus and an electronic device by providing an engine layer including a plurality of space files and an encapsulation layer including a file directory tree of a space file structure; where the engine layer responds to a data management operation performed for a target space file of the file directory tree output by the engine layer, and a target magnetic disk space corresponding to the target space files is determined through the address association list of the encapsulation layer, and data management is performed on the data in the target magnetic disk space. Thereby, different data can be isolated by different space files when entering through the engine layer, which ensures that security issues such as leakage of the data in the magnetic disk will not occur.
