Abstract

The invention discloses a file processing method, device and equipment and a storage medium, and belongs to the technical field of storage. According to the invention, the index file is introduced; the storage position of each file is recorded, and the storage position of the file can be directly obtained from the index file every time the file is read, so that the data of the file is read from the storage space, a series of index operations in a file system are bypassed, and the data reading efficiency and the file processing efficiency are greatly improved. Moreover, by reducing the index operation, the bottleneck problem caused by the index operation is avoided, and the storage performance and stability of the file system are improved. Furthermore, when the file is damaged or lost, thestorage position of the damaged or lost file can be obtained from the index file, so that the data of the lost or lost file is read, the data loss is avoided, and the robustness and stability of the file system are ensured.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a file processing method, device, equipment and storage medium. Background technique [0002] A file system refers to a system that manages, organizes, and stores a large number of files. After a computer device stores files in the file system, it can process the files in the file system by running the file system, such as reading, writing, and deleting files. documents etc. [0003] Each file in the file system is stored through an index partition and a data partition. The index partition is used to store the metadata of the corresponding file, and the data partition is used to store the data of the corresponding file. In addition, the file system also includes a directory file to record the file name And the mapping relationship between index partition numbers. At present, when various processes are performed on files in the file system, a series of indexing operations need ...
