• Easy-to-use: The component includes an intuitive interface design with built-in enumerations, types and constants that work with your IDE's auto complete features to simplify coding. It contains F1 context help, a quick start guide and samples in several different programming languages to get you started quickly. It seamlessly integrates with VB6, VC6, VB.NET, C#, VC.NET, Borland Delphi, Borland CBuilder and other programming environments that support ActiveX technology to offer the broadest possible compatibility.
• Powerful: Just a few lines of code let you add zip compression that rivals that of leading zip utilities, including: BZip2/LZMA/PPMd compression, multipart archiving, ZIP64 large file support, WinZip AES encryption, self extract, memory compression & Unicode support. All operations support multithreading and asynchronous calls. And all this comes with complete control... the component features events that keep your application informed of operations progress and allow your application to take corrective actions. You can also abort an operation at any time.
• High Performance: Based on the ATL framework and highly optimized code, Bricolsoft Zip is one of the top ActiveX zip libraries in terms of speed. That makes it ideal for jobs that require speed and efficiency.
• Simple-to-Deploy: Bricolsoft Zip consists of a single DLL that contains all required functionality. This simplifies deployment because you don't have to worry about complex dependencies. Just include the DLL and you're done.
• Fully compatible: Bricolsoft Zip is fully compliant with WinZip 12 and the PKZIP 2.04g & 4.5 formats. The files that the library creates can be read by all major zip utilities.

Included: CakListview, CakTreeview are included to show contents of archive.

And some functions to simplify the work of making archiver.

The TDIZipWriter class has plenty of methods to write various types of data to the archive, including Files, Streams, Strings, and Buffers. Multiple writes to the same archive entry are possible. Direct streaming allows objects to stream their data directly to a TStream interface using their native WriteToStream procedure.

TDIZipWriter writes all data directly to the archive, avoiding any temporary memory or file storage. TDIZipWriter also supports encryption and .zip comments, stores long file names and relative path information, compiles straight into your .exe (< 55 KB), consumes little memory only and has an excellent performance.

The DIZipWriter package includes full HTML Help with demo projects. The Demo version shows a once-only reminder when run outside the IDE.

UnZip makes it very easy to extract selected files from ZIP archives, either to disk or into memory. It also offers a basic Grep-like function to search for strings in the archived files. This wrapper was written for UnZip 5.5.0. It was created with Delphi 7, but should work in any other version too.
