Decompressing a zipped file

My application is working fine for Decompressing file which file has already compressed using winzip. But if the zipped(compressed) file size is 2GB, it is giving an IO exception.

I came to know that Truezip will work fine for upto 4GB Compressed file.

Can you anyone suggest me how I have to handle if a compressed file having the size of more than 4GB .

Thanks
