Abstract

Global filesystems and new file transfer protocols are a great need and 
challenge in the presence of drastically growing networks. In this paper 
we present results obtained from an investigation of access to public files
which took place over three months. This work visualizes first results
on the popularity of public ftp files, on common operations
(deletions, updates and insertions) to public file-archives and on 
encountered filesizes. An index for measuring 
locality of reference to a resource is also proposed. 
The results show that most file transfers relate to 
only a small fraction of the files in an archive and that a considerable part
of the operations to public files are updates of files. Further results
are presented and interpreted in the paper.
