The traditional file service is no longer sufficient for providing reliable and smart service to users as roaming in ubiquitous computing environments. In this paper, we propose a smart push file service model, called PushFS, which employs a push-oriented file service for ubiquitous storage. The design of PushFS introduces user-profiles to identify the environmental-context and file-semantics for retrieve, and hoards virtual directories and virtual files into lightweight working sets on-demand. We indicate that the dynamic metadata-aware file selection and organization capability increases efficiency of the file service and improves the tradeoff between proactivity and transparency. We then implement a prototype system to validate our model, which shows that PushFS is adequate to ubiquitous storage with high efficient and proactive file service.
