A C/C++ library based on the Zlib library, that currently supports zip and unzip needs to be updated to? use ZIP64 to uncompress files? compressed using ZIP64 and also to compress? files using? ZIP64 if? input? files? exceed the 4GB? size limit.? Support also needs to be added for uncompressing files? compressed using 7z, and rar formats.
All of the sample source code? and specifications required to implement this are already available? freely on the internet as open source. This should be easy for someone who has prior experience working with compression algorithms.
