Systems and methods for manipulating and managing computer archive files

a technology for managing and manipulating computer archive files, applied in the direction of code conversion, data processing applications, instruments, etc., can solve the problems of increasing the overhead of processing (compressing/uncompressing) files, burdening users with standalone programs, and affecting the processing efficiency of zip files. to achieve the effect of facilitating the handling of downloaded zip files

Benefits of technology

Enables users to efficiently manage zip files within the Explorer environment, minimizing system overhead, providing secure file authentication and encryption, and optimizing compression methods, while eliminating the need for separate compression programs and reducing file transfer times.

Problems solved by technology

That meant that users were required to use standalone programs to compress and uncompress their files.
The same problem occurs when trying to work with and manipulate compressed archived files.
This process is often burdensome and inconvenient to the user.
Many of the above programs have increased performance overhead in processing (compressing / uncompressing) files continuously in and out, and it is often difficult for a user to determine if he is in a zip file or rather in a folder.

Embodiment Construction

[0037]FIG. 1 is a diagram illustrating the software components underlying the system 10 of the present invention. There are three basic components of the underlying software. These components are the user interface (UI) 20, the file management (FM) component 30, and the compression / extraction engine (CE) 40.

[0038] The lowest level component is the compression / extraction engine 40. The compression / extraction component 40 consists of the actual compression, extraction, and crc-32 algorithms. These are written as a set of portable C language routines, with higher level C++ routines interfacing with the higher level file management component 30. The file management component 30 consists of the central directory 32 which holds a cached tree-like structure of the archive independent of the actual archive type. Actual archive implementation is used by the central directory 22 to read / write data to the archives 34 and the user interface 20. The central directory 32 consists of folder objec...

Abstract

A computer program for managing and manipulating archive zip files of a computer. The program includes a system and method for opening, creating, and modifying, and extracting zip archive files. The program is fully integrated into Microsoft Windows Explorer and is accessed via Explorer menus, toolbars, and / or drag and drop operations. An important feature of the program is the archive manager which may be used to open a zip file, create a new zip file, extract zip files, modify zip files, etc. The program is integrated into Microsoft Windows Explorer using the shell name space extension application program interface developed by Microsoft.

RELATED APPLICATIONS [0001] This application is a continuation of U.S. patent application Ser. No. 10 / 970,897, filed on Oct. 21, 2004, which is a continuation of U.S. patent application Ser. No. 09 / 803,355, filed on Mar. 9, 2001, now U.S. Pat. No. 6,879,988, which claims the benefit of U.S. Provisional Patent Application No. 60 / 187,969, filed Mar. 9, 2000.FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] [Not Applicable]MICROFICHE / COPYRIGHT REFERENCE [0003] [Not Applicable]BACKGROUND OF THE INVENTION [0004] The present invention relates to managing and manipulating computer archive files, and more particularly to a system and method for managing and manipulating zip files through a computer program integrated into Microsoft Windows Explorer. [0005] Compression of computer files has been around for years. Compressing files can save tremendous amounts of disk space, and transfer time when downloading files from the Internet or transferring files through email. These days, almost any ...
