Zip
Pardon if it's a dumb question, but is it possible to

1. Use the new D zip module to read files made with WinZip
2. To write files in WinZip form

Also, can the D zip module apply Winzip compatible, or other, password
encryption.

I know many zip formats share a commonality somewhere deep, which is why
WinZip can open several kinds, but I cannot remember the details.

Yes. (as long as you stick with the 'deflate' compression method, which is
the default, and do not use encryption, multi-disk zips, etc.)

Yes.

Password encryption is not supported. It could be added if there's a lot of
interest in it. But anyone using it should know that there are numerous
*effective* zip password crackers out there. Zip password encryption will
not stop anyone capable of using google.

There are older zip formats supported by the comprehensive zip programs, but
I doubt many care about them. If I'm wrong, support for it could be added.

Yes, please. Let's have it. I promise to donate the tool I write if we get
password support. :)

May I ask what the application for password support is? Maybe I can talk you
out of it <g>.
