DETERMINING REDUNDANCIES IN CONTENT OBJECT DIRECTORIES

摘要

A system for identifying files and for determining redundancies in content object directories (figure 1) accesses multiple files stored in memory (104). For each accessed file, a corresponding fingerprint is detrmined using Fast Fourier Transform (108). A frequency representation each file is then associated with a name for each file in a directory such that the frequency representation for the file is accessible via the directory. The fingerprints of the file are compared to identify redundancies (112,116,120), which are subsequently removed or deleted (124).
