Abstract

The invention relates to a storage space arrangement method and device. The method comprises the steps of acquiring a to-be-arranged area in a disk, wherein the to-be-arranged area comprises a use area and an idle area adjacent to the use area, the use area is composed of at least one use section, the idle area is composed of at least one idle section, and each of the use section and the idle section comprises at least one block; determining target moving data in the use area; and moving the target moving data to any idle area to increase the number of blocks included in the idle area where the data is not carried in. The method is applied to a scene with low disk storage and serious fragmentation, and a continuous storage space cannot be found to carry out fragmentation work, and according to the method and the device, the to-be-arranged area consisting of the use area and the two idle areas adjacent to the use area is found, and the target moving data in the use area is moved to theidle areas, so that the continuous available storage space is enlarged, and the fragment arrangement work can be effectively carried out.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a storage space organizing method and device. Background technique [0002] The storage space of the disk is divided into multiple data blocks, and the data area of ​​each data block can store data. When data in a certain data block is deleted, the data block forms an empty block. But this empty block cannot be utilized by other programs, so this empty block has just formed " debris ". Contents of the invention [0003] In order to overcome the problems existing in the related technologies, embodiments of the present disclosure provide a storage space organizing method and device. Described technical scheme is as follows: [0004] According to the first aspect of the embodiments of the present disclosure, there is provided a method for organizing storage space, including: [0005] Obtaining an area to be organized in the disk, the area to be organized include...
