Relation-Based File Management for Portable Device

As storage capacity in CE devices has been increased, the number and type of files has been increased accordingly. But traditional file systems generally use hierarchical directory/file structure to organize files. When we want to store and retrieve a file, we should know the name and location of the file exactly. And only one access path can be allowed to users. These file systems are not adequate to manage files of portable storage. We present WebFS to effectively manage files stored in mobile storage and to provide users with a convenient way to retrieve files. WebFS represents complicated information of files by using extended file metadata and provides various and effective way to access files by using inter-file relationships among files.
