Abstract
A method for dynamic caching of data in a disk based operating system. Upon the opening of a file, an access log is created. The access log is updated while accessing the data from the file. Range of access and access time are determined from the access log, and based on the range of access and access time, it is determined whether access of the file was sequential and within a predetermined access time. Based on this determination, a predetermined amount of data from the file is stored in a cache memory when access was sequential and also within the predetermined access time.
