Abstract
Apparatus and programmed method is disclosed, providing for the creation of a circular file of use in conjunction with the UNIX.TM. operating system or other layered and modular operating system architectures. The circular file uses an inode field to identify the file as circular and writes fill data to the file to allocate physical blocks to the file at the time of its creation. Thereafter, blocks already allocated to the file are re-allocated when more file space is needed and the file size does not increase.
