"The same volume can not be used as both source and destination" when extracting the zip file using winzip

[najes]

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.compress_method	MZ_COMPRESS_METHOD_STORE
options.compress_level	MZ_COMPRESS_LEVEL_DEFAULT
options.append	1
options.overwrite	1
options.follow_links	0
options.store_links	0
options.include_path	0
options.zip_cd	0
options.aes	0
options.encoding	MZ_ENCODING_UTF8
options.disk_size	512*1024
options.cert_path	NULL
options.cert_pwd	NULL

Thanks!

Please attach a zip file that reproduces the problem.

Here is one of the zip file

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.
