Embodiment Construction

[0026] The general inventive concept of the present invention is to provide a file management method in the computer system: segment the file written by the user into two parts, store one part in the predetermined partition of the local disk, and store the file in the predetermined partition of the local disk. The other part of it is stored on the server, and the storage information of the two parts of the file is stored in the file to be written by the user; when the user intends to read the file data previously written in the aforementioned manner, from writing to The file indicated by the user reads the storage information of the file, reads part of the file data in a predetermined partition of the local disk according to the storage information and requests another part of the file data stored on the server from the server, and then according to the read part of the file data And another part of the file data requested to reconstruct the file data actually written by the us...

Abstract

The invention provides a file data writing method, and a file data reading method and device. The file data writing method comprises steps of obtaining a file writing request including a file identification and a memory buffer address, obtaining file data to be written according to the memory buffer address, segmenting the file data into two or more data fragments, writing data of the first fragment comprising part of the two or more segmented data fragments in a preset partition in a local disk, sending data of the second fragment comprising the other part of the two or more segmented data fragments to a server, receiving the storage result of the data of the second fragment from the server, and writing data offset values and data size of all data fragments and file store data of the store address in a file indicated by the file identification, wherein storage positions of all the data fragments in the data of the second fragment are preset positions on the server.

Description

technical field [0001] The invention relates to a file management technology, in particular to a method for writing file data, a method for reading file data and a device for realizing the method. Background technique [0002] The existing file management technology is to store the complete file in the hard disk, when writing the file data, directly save the written complete file data in the specified path; when reading the file data, since the file is complete Stored in the hard disk, the system directly provides the complete content of the file to the user. [0003] However, this file management technology has the problem of not being able to guarantee file security, and the file is easy to be completely stolen, even if it is encrypted, there is still a risk of being cracked. Contents of the invention [0004] The object of the present invention is to provide a method for writing file data, a method and device for reading file data, by performing fragmentation processin...
