However problem arises when number of file increases. In this case organizing and managing these files become tiresome work. This paper presents a framework to annotate and search files on mobile devices. To improve a searching at mobile devices semantic file annotation is used which annotates the file according to their different contexts. In proposed framework file annotation and searching is performed by annotating the file with their vital attribute which are extracted from the underlying operating system of the device. The file search can be performed on mobile itself or on Personal Area Network (PAN) also by the use of Bluetooth.
