The zip file created by minizip 2.9.0 cannot be extracted on the same volume?
I keep getting warning below if i tried to extract zip file using winzip on windows file explorer (it works on 7zip though) :

Did i miss something on the zip options part?

options.overwrite1

options.store_links0
options.include_path0
options.zip_cd0

    Please attach a zip file that reproduces the problem.

    It looks like you are appending entries to the zip file. Can you please share the command lines that you used to create this archive?

    int32_t err = 0;
char* szFile[ ] = { "TEST.EXE", "TEST.INI", .... }
for(int i=0, i<(sizeof(szFile)/sizeof(szFile[0])), i++)
{
  err = (minizip_add(path, password, &options, 1, &szFile[i]));
  if(err == !=MZ_OK)
  {
    .....
  }
}

    The minizip_add function is not intended to be used in this manner. You should be using the logic inside minizip_add and calling mz_zip_writer_add_path for each entry you want to add, otherwise you are opening the zip file over and over to add each file.

    It is likely that Windows Explorer does not support split disks. If compatibility with Windows Explorer zip tool is important to you, then specify 0 for disk_size.
