i along with several others here use dynazip with vfp 5.0a.
it works great as far as i can tell.
i use the ocx interface and wrote a wrapper vcx for it so that the programmers in our department could just use dynazip in a way consistent with our other components.

we use several zip functions - zipping ( with path & without, recursing & not, with progress bars and not, spanning & not, long filename & not ), unzipping ( same functions with zipping but in the reverse order ). also we can delete files from a zip and add files to a zip. i was also able to write a function to gather info from a zip file into an array very similar to adir.

i found that the control works great and their tech support is very good also.
they offer direct support for vfp also.



>I need a zip program to include with my software. I am use to using Winzip which was very easy to use for personal use, but never it used it in my programs. Has any body had experience Dynazip, or used any other zips in their programs? Is Dynazip easy to use? Was it reliable? I am using VFP 5.0a, and soon to be VFP 6 on Windows 98.
