Zipping Folder to a .zip

Hi,

I am trying to write a backup program what i would like it to do is zip up a folder then copy the .zip to a second hard drive.

Does anyone know if its at all possible to zip up a folders contense to a .zip from c++? If i cant do that i think i would automate the process of zipping it, e.g open winzip then get my program to fill in nessery data. So if i cant zip up from my prog can someone tell me how i can press a button in another program, i suspect i would need to find the buttons ID then send a command message to winzip or somthing similar.

Any help will help :rolleyes:

Thanks

look up huffman coding.

You could also hack your way through by using command line options to minimize and manipulate Winzip.

if you fail to understand huffman coding then use Zlib. It is a C libary for compression.
