Probllem extracting Zip files greater than 2 GB size

[EDN Admin]

<br/>
By using the below sample code, tried to extract a zip file having size more than 2.5 GB(contains 6 folders in it). But the get_count is returning only 3 as number of files in it and extracting only 3 files. Can anyone please through some light here or suggest
any other VC++ or C++ library for zip file( size greater than 2GB) decompression. Thanks in advance.<br/>
