However, many of the current navigation based interfaces are unable to support efficient retrieval of this information. We develop a file system crawler, and use this to conduct a user study to characterise the structural features and temporal usage patterns of file systems. Based on these findings and the extensive prior literature, we develop a spatially consistent representation of entire file systems which is augmented with colourcoded tags allowing efficient access to temporally relevant target folders within the file system (SCOFT). We conduct a user study to evaluate the effectiveness of this technique and the supporting techniques developed. Our findings show that SCOFT allows users to revisit files 3 times faster than when using a standard file browser.enAll Right ReservedTheses / Dissertations
