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.

Claims

1. A method for compressing a data file, said method including:

providing a graphical user interface using a browser;

providing a .zip management application, wherein said .zip management application allows a user to compress a file for inclusion in a .zip archive using said graphical user interface;

identifying a data file to be compressed using said graphical user interface;

providing a plurality of user-selectable compression options; and

compressing said data file using one of said plurality of user-selectable compression options selected by a user.

2. The method of claim 1 wherein said browser is Microsoft Windows Explorer.

3. The method of claim 1 wherein said plurality of compression options include .zip compression options.

4. The method of claim 3 wherein said plurality of compression options include a Deflate compression option.

5. The method of claim 4 wherein said plurality of compression options include a first Deflate compression option operating at a first compression level and a second Deflate compression option operating at a second compression level, wherein said first compression level is different from said second compression level.

6. The method of claim 1 wherein said plurality of compression options include a DCL Implode compression option.

7. The method of claim 6 wherein said plurality of compression options include a first DCL Implode compression option operating at a first dictionary byte size and a second DCL Implode compression option operating at a second dictionary byte size, wherein said first dictionary byte size is different from said second dictionary byte size.

8. The method of claim 1 wherein said plurality of compression options include a compression option wherein said data file is stored without compression.

9. The method of claim 1 further including:

providing a plurality of user-selectable encryption options; and

encrypting said data file using one of said plurality of encryption options selected by a user.

10. The method of claim 9 wherein said plurality of encryption options include an asymmetric encryption option.

11. The method of claim 10 wherein said asymmetric encryption option includes a public key based encryption option.

12. The method of claim 11 wherein said public key uses the X.509 format

13. A method for providing a plurality of compression options for use with a file, said method including:

providing a graphical user interface using a browser; and

providing a .zip management application, wherein said .zip management application allows a user to compress a file for inclusion in a .zip archive using said graphical user interface,

wherein said .zip management application provides a plurality of compression options for use with a file.

14. The method of claim 13 wherein said browser is Microsoft Windows Explorer.

15. The method of claim 13 wherein a user selects one of said plurality of compression options to determine a selected compression option.

16. The method of claim 13 wherein said selected compression option is applied to said file.

17. A method for determining a compression option for use in compressing a data file, said method including:

identifying a data file using a compression management application;

determining a compression option to apply to said data file, wherein said compression option is determined from a plurality of compression options available at said compression management application.
