If a system runs mostly database applications, it may be more efficient for the operating system to implement a database-type file and provide operations, rather than making each program implement the same thing (possibly in different ways). For general- purpose systems it may be better to on...
Metadata management.The file system maintains metadata about each file and directory, including its name, size, creation and modification dates, permissions, etc. Directory structure.The file system organizes the files in a hierarchical directory structure, allowing users andapplicationsto easily navigate ...
Most file systems organize files in a directory hierarchy, with a file's location described by its path within the directory structure. The directories -- folders in Windows -- are organized into an inverted hierarchical tree structure, with the root directory at the top. Each file is placed ...
The FAT file system limits filenames to the 8.3 naming convention, meaning that a filename can have no more than eight characters before the period and no more than three after. Filenames in a FAT file system must also begin with a letter or number, and they can't contain spaces. Fil...
