Abstract
Oftentimes, computer files, information packets, and the like share identical data portions that cause duplicate storing. The files and/or packets can be logically divided and checks can be performed to determine if there are shared portions. If shared portions exist, then as opposed to making a duplicate copy of information, a pointer can be produced that identifies where the portion is saved. In addition, pointers can be used in compression of information such that a compressed file can identify an original copy—the original copy can be used to decompress the information.
