Method and system for arranging file chips

Abstract

The invention relates to file fragmentation sorting out, and provides a method for sorting out file fragmentations and a system thereof by aiming at the disadvantages such as high cost of the existing methods for sorting out the file fragmentations of a mobile terminal. The method comprises the step of allocating continuous storage spaces, and the step of transferring files with the fragmentations to the allocated storage space. The invention also provides a system for sorting out the file fragmentations. Fragmented files are stored by an empty block, and no additional memory is needed, thus the total cost can be reduced. The storage addresses of the fragmented files are updated to the addresses in the empty block, which causes the files with the fragmentations to be copied only once, and does not lead to an excessive processing burden. As only the files with the fragmentations are sorted out, the sorting efficiency is higher. Furthermore, an erase operation is performed only when the erase condition is satisfied, thus the performance degradation caused by frequent erasures can be effectively avoided. A threshold can be adjusted according to the number of the empty blocks and the system burden, therefore the process for sorting out the fragmentations can be optimized.

Description

technical field [0001] The present invention relates to file defragmentation technology, more specifically, to a method and system for defragmenting files. Background technique [0002] The continuous progress of storage technology makes the capacity of the memory larger and larger, while the volume is constantly shrinking. Large-capacity portable storage is favored by users and has been widely used in people's work and life. [0003] At present, the capacity of memory configured in mobile terminals such as smart phones and PDAs (Personal Digital Assistants) is generally above 1G. In addition to storing commonly used audio files, more and more users begin to store Save documents, forms and other office files in the computer. Such office files are often read and written frequently and in large numbers, but the space occupied by each file is very small. Therefore, these office files are prone to file fragments during the process of repeated reading and writing. The so-calle...
