>Now I use pkzip and pkunzip programs i my applications . I'm looking for library for VFP
I second what Larry replied. DynaZip integrates extremely well into VFP apps. The documentation is quite good and includes VFP examples. If you decide to go that direction, I have greatly improved my DynaZip class that I will be uploading here soon that you can download and use with the libraries.
