Yup snkr is right. You need 64 Bit OS in order to download or upload 2 GB+ files.

If you are talking about the File Size Limit shown while you choose to upload a file, then you can increase it by editing the max_file_size limit in hosts/upload/FILEHOST.index.php OR hosts/upload/FILEHOST_member.index.php

Where FILEHOST refers to the domain name of the filehost you want to increase the limit for.
