Problems solved by technology

Although the storage medium technology is constantly improving, the data storage track has become very narrow and the data storage capacity has become larger and larger, and the current data recovery or erasing technology does exist when the track becomes denser or narrower. When the physical microscopic magnification recovery technology fails; when the data storage capacity is getting larger and larger, the method of overwriting and erasing due to multiple or repeated writes is inefficient, which hinders the user's work efficiency and brings time or economic losses to the user. loss

Embodiment Construction

[0022] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the present invention will be further detailed below in conjunction with the accompanying drawings illustrate.

[0023] Depend on figure 1 As shown, a method for fast file erasure of anti-recovery software, specifically includes:

[0024] S101, search the file system index table of the target file and determine the data storage sector location of the target file by analyzing the path of the target file; wherein, in the analysis of the target file path, the file system index table of the search target file includes, from the root directory The file system index table starts to parse the file system index table of each layer of directories until the file system index table of the target ...

Abstract

The invention provides a method and a system of rapid file erasure of anti-recovery software. The method includes: building a file system index table of an object file through the mode of path resolution; destroying the sector where the object file data is positioned through the resolution of the file system index table of the object file; and deleting an index corresponding to the object file of a parent directory. The invention further provides the system suitable for the method, through the system, the effect that when data storage capacity becomes larger and larger, or magnetic tracks are relatively narrow, a user can rapidly carry out the rapid and thorough file erasure of the anti-recovery software can be achieved, and time and economic losses are effectively prevented.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a method and system for fast file erasing of anti-recovery software. Background technique [0002] The storage data track of the current file storage medium is relatively wide, and the data is written inconsistently on the track every time, which leads to the fact that the data written later does not completely cover the data written before, and physical microscopic amplification technology can be used Perform bit-by-bit recovery of data that appears to be overwritten but is actually not overwritten; therefore, many existing standards for file erasure involve multiple write overwrite erasures to achieve the purpose of indiscriminately overwriting data storage tracks. Although the storage medium technology is constantly improving, the data storage track has become very narrow and the data storage capacity has become larger and larger, and the current data recovery or erasing t...
