ABSTRACT:
A multi-user computer system having methods which provide improved file management by reading an additional amount in a single I/O (Input/Output) operation during file processing is described. A method for storing and retrieving a plurality of information files includes storing the plurality of information files as a single disk file, where the disk file includes at least one storage block of a uniform size for each of the information files. The information files themselves may be of a variable file size. Within the single disk file, the method stores a directory of entries about the information files, each entry describing a location for one of the information files. The method provides steps for retrieving a desired information file by locating a storage block having the desired information file. The steps include reading from the storage block an amount of data equal to the file size of the information file plus an additional amount, in a single I/O operation. In this manner, the method improves system performance by reducing the total number of I/O operations required for file processing.
