A Compression Component by Dart Communications

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 the PowerTCP Zip Compression Tool also contains self-extraction and AES encryption capability! If all these great features just aren't needed right now, review our ZipLite version for simple zip/unzip functionality.

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