ข้อมูลตัวคั่น 4

File Separator was used in computer terminals, printers, text processing systems, and telecommunication equipment. Its main purpose was to indicate the boundary between files or data parts within one stream, especially when they were transmitted or saved on a single physical device. It also allowed programs to determine the boundaries between different files or data blocks and process them accordingly.
