Hi May be my question seems to be Irrelevant to this forum but your answer can help me. I am making a file system it is working well in case of files but i donot know how to store directies in it. I searched a lot. These things i know from research 1. Directories are saved in a similar way as the file are saved in the Root Directory Entry with a on directory bit in the attribute field. 2. There is "." and ".." pointers .pointer point to it self and ..pointer points to its parent. but where they are saved in the name field???. Where the parent address is saved (if it is saved in the starting cluster area then where the start of the directory is saved as i read it that subdirectory take at least one cluster) thanxs Regards Farhan Arshad
