minizip.exe: zip archive with empty directory?

I try this command :
minizip -1 ..\package.zip *
in current directory there are some empty folders but these is not added into archive.

OS: Windows

Added support for directory entries in minizip. #257

I added support for this into the dev branch.

I try:
minizip -1 -i ..\package.zip *
but the empty folders now added as normal zero-byte file not directory?
am I missing something?

The directory file attribute has been set for those entries in the zip file. If you are using -l I have added attributes column so you can see it.

if I list it:
minizip -l ..\package.zip
I get:

supposedly "new" and "save" are empty directories not a file.
this package.zip also impossible to extract due it is illegal for Windows to have directory and file of the same name "template"

please reopen.

I don't think you are using the latest version from the dev branch. It has an attributes column.

I did use dev branch just missed the printout commit (83bce6e)
The problem still there:

Fixed print out of directories. #257

Fixed directory compression method.

I have changed it so it shows a slash at the end if it is a directory. If you still have problems can you explain how you are seeing those directories as files and also attach your zip. Thanks.

It is still treated as file, here the zip file (I replaced sensitive data with dummy text)
package.zip

Googling around I notice same problem also happen to older .NET sharpziplib
https://stackoverflow.com/questions/18363187/how-do-you-add-a-folder-to-a-zip-archive-with-icsharpcode-sharpziplib
https://sourceforge.net/p/sevenzip/discussion/45798/thread/b246352d/

Opening the zip with hex editor it doesn't have slash at the end in the zip index. So there is mis-detection of directory? 7zip created zip does have slash

Append slash to directories for compatibility. #257

Okay I have appended a slash to the filename for directories.

cool, works now!
tested with miniz 1.1.5 too.
