ASCII Character: File Separator

About the File Separator Character

ASCII code 28 (0x1C) represents the File Separator (FS) control character. This is a non-printable character defined in the original ASCII standard (1963). It belongs to the information separator group, used to structure data into hierarchical levels for processing. Control characters occupy codes 0–31 and 127 in the ASCII table and were originally designed for controlling hardware devices, managing communication links, and formatting text output. While many control characters have become obsolete with modern computing, several like LF (Line Feed), CR (Carriage Return), TAB, and ESC remain essential in everyday programming and text processing.
