File system with data processing function and use method thereof

The invention provides a file system with a data processing function and a use method of the file system. The file system with the data processing function comprises a system process, and the system process is used for starting the file system, and data processing can be carried out. When an application process sends out a data processing request, the system process receives the data processing request sent by the application process based on special files, the data processing request is analyzed, data processing is completed, and a data processing result is fed back to the application process based on the special files. The special files have special character file names which are not identical to those of traditional files, and the special files are set in all paths of the file system with the data processing function respectively. According to the file system with the data processing function, data migration in the data access process is greatly reduced, meanwhile, the read-write and access speed of the files is improved, limited DRAM resources are saved, and therefore the I/O performance of the system is improved.
