So close, yet so far.
I used Craig Boyd's VFPCompression to extract and then rezip them up --> but it refuses to zip the \_rels\.rels folder/file combination (the folder is there, just no file inside of it). I guess .rels is not really a legal file name, so I'll have to punt that nice little library that Craig has made available. I'll have to try another zip library of some sort.
I have 7-zip and that seems to work from the windows file manager, but I can't find a good (easy) reference on calling it from vfp9 to zip it up. If anyone has ideas or a link, let me know.
Thanks,
Kevin
