# Files & The C-Programming Language

There are times when a program needs to access disk-based storage systems. Text files or data is normally stored or retrieved from a floppy or hard drive. On the QL, data files can also be transferred across the serial ports, in the same manner as a floppy drive. The subject of this article is the necessary file handling required to access the QL input and output(I/O) channels.
