Hi. I love the support for loading ZIP files added in the new release. I see you use a 7-Zip DLL to make this work. I was wondering if you could point me in the right direction to the Delphi interface for the 7-Zip DLL so I can also save back changes made to zip file with and without password protection. Thanks!

Write support for zip files is certainly on the to-do list, just waiting to see how much interest there is in the feature.

If you add the ImageEn source folder to your Delphi path, and open iexSevenZip.pas you will see that write support can be enabled by defining IESupportCompression. Then you can follow the ZIP methods in imageenio.pas and iemio.pas and create your own I7zOutArchive.

Thanks! I will take a look and see what is involved. Obviously I would love to see support in the future for this feature in the future!
