Fast development in low end devices permits so many extra aspects including huge storage capacity, sharing of data, formation of network, etc. User can use these aspects very efficiently. When data size is limited searching a particular file can done easily but difficulty comes when data size increases and it involves large collection of mobile nodes. In that case arrangement of data i. e. data organization and management become irritating work. However file system of devices itself provides a way to store similar files separately; still it becomes irritating when number of files increases. Even poor UI (User Interface) increases more difficulty in case of file retrieval. This paper presents model that allows user to annotate files and to search a file of interest on mobile devices. File is annotated using their spatial, common and temporal circumstance which are extracted from underlining operating system and used as a metadata which is used for searching a file of interest. The file search can be achieved on mobile itself or on other mobile also those are connected in Personal Area Network (PAN) using Bluetooth. The proposed model allows file annotation, file search, creating PAN (Personal Area Network), file sharing, etc.
