What is the process called where files are divided into smaller chunks during distribution?

The process of dividing files into smaller chunks during distribution is referred to as "Chunking." This method is commonly used in data transfer protocols and systems to enhance efficiency and manageability. By breaking down large files into smaller, more manageable pieces, the system can optimize the bandwidth and improve the transfer speed, particularly in environments where network reliability may be an issue. It also allows for better error handling, as only the affected chunks can be retransmitted if a problem occurs during the transfer. This process is essential in various applications, including cloud storage, content delivery networks, and streaming services, where large files need to be transferred quickly and reliably.

The other concepts, although they might relate to file handling in some capacity, do not directly describe the act of dividing files for distribution purposes in the same way that chunking does. Thus, chunking is the most accurate term for the described process.
