PowerTCP Zip Compression for ActiveX lets you add high-speed, reliable, zip/unzip functionality to your applications regardless of whether you are manipulating files or memory. We've developed our own unique methods and objects that will allow you to work quickly and easily regardless of your project's complexity.

Consulting and Custom Development

From custom protocols to complete client-server solutions, let our experienced staff help with your Zip project. Here are some of the solutions we have delivered.

For those simple jobs, the QuickZip and QuickUnzip methods perform compression and decompression of files with only one line of code! This tool also includes a unique FileStore object, which gives you fine-tuned memory/file support. You will finally be able to move data from a memory buffer to a compressed file or vice-versa and easily extract a single file from a compressed file, display information about an individual file within a compressed file and search inside a compressed file. Now PowerTCP Zip Compression for ActiveX also contains self-extraction and AES encryption capability!

Don't sacrifice speed for performance when you can get them both in the new PowerTCP Zip Compression for ActiveX.
