64-bit file size support

64-bit file size support means that computers can handle very large files, up to approximately 18 exabytes (18 million terabytes). Unlike older systems limited to 4 gigabytes, 64-bit architecture uses a wider address space, allowing operating systems and software to read, write, and manage larger files efficiently. This is essential for multimedia, scientific data, and large databases, ensuring systems can store and process vast amounts of information without issues related to file size limits. In essence, 64-bit support future-proofs storage capabilities by accommodating the growing size and complexity of modern digital data.
