Renaming a file, moving a file (or a subdirectory) from one directory to another and deleting a file are examples of the operations provide by the file system for the management of directories. Metadata operations such as permitting or restricting access the a directory by various users or groups of users are usually included.
The Java RMI and Java EE APIs use the JNDI API to look up objects in a network. [3] The API provides: a mechanism to bind an object to a name; a directory-lookup interface that allows general queries; an event interface that allows clients to determine when directory entries have been modified
The logical file system layer provides relatively high-level access via an application programming interface (API) for file operations including open, close, read and write – delegating operations to lower layers. This layer manages open file table entries and per-process file descriptors. [8]
Directory (D): The entry is a subdirectory, containing file and directory entries of its own. Reparse Point (L): The file or directory has an associated re-parse point, or is a symbolic link . Offline (O): The file data is physically moved to offline storage (Remote Storage).
Each directory is a list of directory entries. Each directory entry associates one file name with one inode number, and consists of the inode number, the length of the file name, and the actual text of the file name. To find a file, the directory is searched front-to-back for the associated filename. For reasonable directory sizes, this is fine.
File descriptors for a single process, file table and inode table. Note that multiple file descriptors can refer to the same file table entry (e.g., as a result of the dup system call [3]: 104 ) and that multiple file table entries can in turn refer to the same inode (if it has been opened multiple times; the table is still simplified because it represents inodes by file names, even though an ...
The contents of the entries in a subtree are governed by a directory schema, a set of definitions and constraints concerning the structure of the directory information tree (DIT). The schema of a Directory Server defines a set of rules that govern the kinds of information that the server can hold. It has a number of elements, including:

A filename or file name is a name used to uniquely identify a computer file in a file system. Different file systems impose different restrictions on filename lengths.
