This is the glossary of the common filesystem features table. The intention of this table is to provide an at-a-glance list of features and specifications for each filesystem. Inventor List the names of those credited with the design of the filesystem specification. This should not include those responsible for writing the implementation. Name The full, non abbreviated, name of the filesystem itself. Native operating system The name of the operating system in which this filesystem debuted. Partition identificator The partitioning scheme and marker used to identify that a partition is formatted to this filesystem. Bad sector allocation Describe how the filesystem allocates and isolates bad sectors. File allocation Describes how the filesystem allocates sectors in-use by files. Directory structure Describes how the subdirectories are implemented. Namespace Lists the characters that are legal within file and directory names. Maximum filename size The maximum number of characters that a file or directory name may contain. Maximum files The maximum number of files the filesystem can handle. Maximum volume size The maximum size of a volume that the filesystem specification can handle. This may differ from the maximum size an operating system supports using a given implementation of the filesystem. Dates handled What type of dates and times the filesystem can support, which may include: Creation date This is the date the file was “created” on the volume. This does not change when working normally with a file, e.g. opening, closing, saving, or modifying the file. Access date This is the date the file was last accessed. An access can be a move, an open, or any other simple access. It can also be tripped by Anti-virus scanners, or Windows system processes. Therefore, caution has to be used when stating a “file was last accessed by user XXX” if there is only the “File Access” date in NTFS to work from. Modified date This date as shown by Windows there has been a change to the file itself. E.g. if a notepad document has more data added to it, this would trip the date it was modified. Changed date The date and time related attributes were modified. This may include ACLs and the file/directory name. Backed-up date The date and time when the file was last backed up. Maximum date The maximum year that can be handled by the filesystem, as per the specification. Attributes Lists the basic file attributes available. Named streams
