The addZIP Compression Components are the simplest way to add the industry-standard PKZIP compatible file compression and decompression to your programs. These royalty-free, multithreaded ActiveX/COM components are compatible with all 32-bit development software including Visual Basic 6/.NET, C/C++, Delphi and Visual FoxPro. The addZIP and addUNZIP components have no user-interface so they can be used both in desktop and server applications. Although .ZIP archives can be created (and extracted) in as little as two lines of code, there are plenty of properties to set in order to select the required files, set the compression level and speed etc etc
