File storage method and device, computer equipment and storage medium thereof

The invention relates to a file storage method and device, computer equipment and a storage medium thereof, and relates to the technical field of artificial intelligence. The method comprises the following steps: splitting a to-be-stored file into at least two file data blocks based on the capacity of a unit data block; based on the used capacity of the at least two local storage spaces and the capacity of the unit data block, the storable capacity of the file data block corresponding to each local storage space is determined; and storing each file data block based on the storable amount of the file data block corresponding to each local storage space. The problem that the file reading efficiency is low when a large file storage method is used for file storage is solved, and the access efficiency of the local storage space is improved; meanwhile, the problem that the number of local storage spaces is large when a small file storage method is used for file storage is avoided, the system performance is improved
