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:

receiving a data file at a compression management application;

determining a file type of said data file; and

compressing said data file using one of a plurality of compression options available using said compression management application, wherein said one of a plurality of compression options has been pre-selected for use with said file type.

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

3. The method of claim 2 wherein said plurality of compression options include a Deflate compression option.

4. The method of claim 3 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.

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

6. The method of claim 5 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.

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

8. The method of claim 1 further including:

encrypting said data file using one of a plurality of encryption options, wherein said one of a plurality of encryption options had been pre-selected for use with said file type.

9. The method of claim 8 wherein said plurality of encryption options include an asymmetric encryption option.

10. The method of claim 9 wherein said asymmetric encryption option includes a public key based encryption option.

11. The method of claim 10 wherein said public key based encryption option uses the X.509 format.

12. 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 file type of said data file; and

using said file type to determine 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.

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

receiving a data file;

determining a file type of said data file;

using said file type to determine a compression type to apply to said data file, wherein said compression type is determined from a plurality of available compression types; and

compressing said data file using said compression type.

14. A method for associating a file type with a compression option, said method including:

providing a file type;

providing a plurality of compression options;

associating said file type with one of said plurality of compression options to form a file type compression association; and

storing said file type compression association.
