: A tool by developer Aldo Vargas that can reduce file size by removing foreign language files and other optional data . 2. Compression Techniques

A standard PlayStation 3 game ISO—a bit-for-bit copy of the original Blu-ray disc—routinely occupies between 15 GB and 50 GB of storage space. Titles like Uncharted 3 or Gran Turismo 6 push the upper limits of the medium. For the average user with a 500 GB hard drive, this allows for fewer than a dozen games. Furthermore, emulation requires the host PC to read and stream these massive files rapidly; an uncompressed 40 GB ISO can lead to stuttering or long load times.
