Abstract

Files are fundamental for information storage in a computing system. This chapter explores the user and environment context to improve personal file management. We focus on the user-oriented files in a computer operating system, which are usually operated manually, such as document files, images, and video files. We formalize the dynamics of contexts to sequential signals, called context streams. Each context stream is a one-dimensional function of time. With the model of a context stream, files can be reorganized using a set of discretely sampled streams based on file operation such as file creating, editing, and deleting. We propose and implement a file system with context streams, named ScudFile. We introduce three applications of the ScudFile, file browsing, file searching, and file recommendation, are introduced. The evaluation of time and usability demonstrates the effectiveness of the ScudFile system.
