Embodiment Construction

[0023] Preferred embodiments of the invention will be described in more detail with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. However, the present invention may be embodied in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0024] The usual decompression technology will keep the original compressed data unchanged in the storage space (such as hard disk or tape, etc.) during the entire decompression process. If the original compressed data is too large and the storage space is insufficient during the decompression process, it will cause decompression. fail.

[0025] The present invention proposes a method for reducing storage space requirements during the decompression process. When the method is decompressed...

Abstract

The invention provides a method and a system for reducing storage requirements during decompressing a compressed file. The method comprises the following steps: inputting step: reading a compressed data block in the compressed file; decompressing step: decompressing the compressed data block; outputting step: storing the decompressed data into a decompressed file; and deleting step: deleting the decompressed compressed data block from the compressed file. The method and the system reduces the unnecessary data repetition between a compressed format and a decompressed format, can reduce the requirement on the storage space in the decompressing process, can not greatly change the prior compressing / decompressing arithmetic, thereby being easily integrated into the prior compressing / decompressing tool.

Description

technical field [0001] The present invention relates to computer software technology, in particular, to a method and system for reducing space requirements of storage devices when decompressing compressed files Background technique [0002] File compression is the process of expressing information in an original file using fewer bytes of the file by encoding the information in that original file. File compression is very useful because file compression greatly reduces resource consumption, for example, when information is saved, compressed files can reduce the demand for storage resources, when information is transmitted, compressed files can reduce the demand for bandwidth, and so on. Due to these requirements, compression technology has developed rapidly, and a large number of compression algorithms have emerged. Different compression algorithms will use different compression formats, such as ZIP and RAR formats commonly used in Microsoft Windows operating systems, and gz ...
