Hi Chris,

first of all I would like to say that the idea of using FINFO to obtain file information from a zip archive member is really nice. The implementation and the need of using a sequential read per zip member makes it rather slow when the zipfile contains a combination many file members.. Therefore I have implemented the ZIP member FINFO in such a way, that it is only used if the zip archive contains one single file. Here is the link to the macro I created: https://github.com/paul-canals/toolbox/tree/master/custom/create_zip%20(standalone%20version).

Thanks & best regards,
Paul
