Polar Zip Component is ideal for individual, small business and enterprise software developers and is ready to meet any and all zipping & unzipping challenges you throw its way!

Features

With a wide range of functions, Polar ZIP will meet all the compression & data protection requirements of your applications.

1. Full source code included

• Completely written in Microsoft Visual C++
• Choose between component and source code when implementing Polar Zip into your application;
• You can do further development and / or customization of the products;
• It is included at regular component price;
• Source code license agreement

2. Zip actions

• Create a new zip file;
• Delete files in a zip file;
• Compress entire directories and their contents or a list of directories;
• Compress only files newer than those already in the zip file (Refresh);
• Compress files and add them to a zip file (Update);
• Delete files after zipping them (Move);
• Have specified types of files directly copied into a zip file without compression;
• Include a drive volume label in a zip file;

3. UnZIP Actions

• Decompress files from a zip file;
• Specify the directory where files will be decompressed to;
• Only decompress files that are newer than the ones already existing on disk (Refresh);
• Converts spaces in filenames to underscores while unzipping;

4. Multi-disk and multi-file archives

• Reads and writes zip files that span multiple disks;
• Creates multi-part zip files directly to a hard drive;
• Converts multi-file archives to one single zip file;
• Converts an existing zip file to a multi-file or a multi-disk archive;
• Events during disk spanning: prompting for disks, prompting to erasing disks and so on. The Polar ZIP Component displays on the screen what you want it to display and enables you to use pre-defined dialogs;
• Formats disks before writing on them;

5. Self-extracting features

• Supported use of unbreakable AES encryption;
• Supported use of a password;
• Specify Self-extracting file name;
• Specify ead Me file that will be displayed when running a Self-extraction file;
• Specify xecute After file that will be executed when running a Self-extraction file;
• Specify folder to unzip files to when running a Self-extraction file;
• Specify whether the dialogs will be displayed when running a Self-extraction file;
• Specify whether existing files will be overwritten during unzipping, while the Self-extraction file is running;

6. Memory compression

• Memory compression & decompression;
• Memory to zip file conversion and vice versa;

7. General zip information

• Obtain a detailed list of files in a zip file;
• Use wildcards to specify the files to be processed;
• Specify the name and location of a zip file;
• Events provide data such as the file size before compression, the compressed file size and other information as it becomes available;
• You have full control over zip comments;

8. Tools

• Specify different encryption and decryption passwords for each file if needed;
• Tests the integrity, repairs corrupted zip files and reports any inconsistencies found;
• Converts existing zip files into self-extracting zip files and vice-versa;
• Make the zip file date the same as the newest item;
• Converts text LFs to CRLFs and vice-versa;

9. General process information

• Set the compression level;
• Work on temporary copies of zip files for maximum safety. You can specify the location of the temporary zip file;
• All operations can be aborted;
• Notifies your application whenever a file is being zipped, unzipped, updated, deleted, etc.;
• Provides the status of the progress by file and globally with the data shown as percentages, bytes and file counts;
• You can easily update your progress bars directly with this information;
• Limits file processing based on file dates: does not operate on files modified after/on the date you specify;

10. Compatibility

• Polar ZIP works with all major Windows?development languages and platforms including:
• MS Visual Basic,
• MS Visual C++,
• MS Visual InterDev,
• MS Access,
• MS Visual Basic .NET,
