Hi, we are currently testing the Xceed Ultimate Suite. In one of our projects, where we plan to use Xceed Zip, we have to estimate the expected compression rate of files and folders. Is it possible to do such estimations with Xceed Zip without real compression of the files? If yes, which approach would you advise? Best Regards,Jens Horn

Hi Pascal, the Deflate compression method is actually the default Zipping method, the one that has been around for more than 15 years.  Best regards

I'm working on a program that read large csv files which can be several hundreds MBs. I noticed that compressing those files with zip would reduced the disk space used by 10. I was thinking allowing my program to read zip files as well but only as a pass-through stream so that there is no overhead on the disk or memory usage. I though the ...

I have been searching the site but can not find a definitive answer.  Is it possible to create a multi-volume zip archive that is self-extracting?  If so, at which version was this feature included? Thank you  Erich
