A server (NT 4.0) running PKZIP 2.5 crashed yesterday, and a customer requests their images to be zipped in PKZIP 2.5 format. But; I  do not have a copy of PKZIP 2.5 to install on another server. But, I do have a copy of PKZIP 2.04.
Question is.... if I zip the images with 2.04 will there be a difference in the format that the customer could notice?

Thanks.

As far as Im aware ALL versions of PKZip are backwards compatable? why not download v2.7 then you will have no problems?

Hi,

An earlier version should work. Or why not try one of the many alternatives? I use 7-zip at home (I think it's still freeware) and have never had any problems with zip formats from other programs and I use FilZip at work - we recieve numerous files zipped up every day of all types and FilZip copes fine with them all.

The only other comment I have is that PKWare have proposed a change in Zip format earlier this year. But I doubt very much whether this will mean that older archive programs will have trouble with this format.

David.

You should verify if PkZip 2.04 know long file names, as far as I remember it don't. That will be the difference, because I think PkZip 2.5 know long file names. If you don't archive files with lfn, there is no problem.
