This is the glossary of the Common Filesystem Features table. This is the glossary of the ''common ] features'' table.


The intention of this table is to give a fast to see and compare filesystem features list and should be wrote in any specific filesystem entry in the Misplaced Pages. The intention of this table is to provide an at-a-glance list of features and specifications for each filesystem.


==Inventor== ==Inventor==
Here comes the name of who created the filesystem specification, not having to be the first who implemented it in the real world. List the names of those credited with the design of the filesystem specification. This should not include those responsible for writing the implementation.


==Name== ==Name==
Here comes the full, non abbreviated, name of the filesystem itself The full, non abbreviated, name of the filesystem itself.


==Native Operating System== ==Native operating system==
Here comes the name of the first operating system that included an implementation of the filesystem. The name of the operating system in which this filesystem debuted.


==Partition identificator== ==Partition identificator==
The partitioning scheme and marker used to identify that a partition is formatted to this filesystem.
Here comes the partition identificator, along with the partitioning scheme of it.


==Bad sector allocation== ==Bad sector allocation==
This describes how the filesystem allocates sectors marked as bad. Describe how the filesystem allocates and isolates ]s.


==File allocation== ==File allocation==
This describes how the filesystem allocates sectors used by files. Describes how the filesystem allocates sectors in-use by files.


==Directory structure== ==Directory structure==
This describes how the subdirectories are implemented. Describes how the subdirectories are implemented.


==Namespace== ==Namespace==
This describes the characters that can be used, or not, for the filenames. Lists the characters that are legal within file and directory names.


==Maximum filename size== ==Maximum filename size==
This describes the maximum number of characters that the filename can have. The maximum number of characters that a file or directory name may contain.


==Maximum files== ==Maximum files==
This describes the maximum number of files the filesystem can allocate. The maximum number of files the filesystem can handle.


==Maximum volume size== ==Maximum volume size==
This describes the maximum volume size that the filesystem can handle. 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.
NOTE: This is as the specification says not as any operating system implements this.


==Dates handled== ==Dates handled==
This describes what type of dates can handle the filesystem. What type of dates and times the filesystem can support, which may include:

They can be: Creation, Access, Modified or Changed
====Creation date==== ===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.
This is the date when the file was created.

====Access date==== ===Access date===
This is the date when the file was last accessed for read.
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 is the date when the file was last accessed for write, no matter if no write was really made.
====Changed date==== ===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.
This is the date when anything related with the file, like attributes, ACLs, filename, etc, is modified.

===Changed date===
The date and time related attributes were modified. This may include ] and the file/directory name.

===Backed-up date===
The date and time when the file was last backed up.


==Maximum date== ==Maximum date==
This describes the maximum year that can be handled by the filesystem, as specification says. The maximum year that can be handled by the filesystem, as per the specification.

This describes if the filesystems supports more data streams than the normal one.
This is how ] calls them, ] calls them Extended Attributes and ] calls them forks.


==Per-volume compression== ==Per-volume compression==
This describes if the filesystem supports real-time and transparent compression and decompression of a whole volume. Does the filesystem support real-time transparent compression and decompression of an entire volume.

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

Determines if the filesystems supports multiple data streams. NTFS refers to these as alternate data streams, HPFS as extended attributes and HFS calls them forks.

Per-volume compression

Does the filesystem support real-time transparent compression and decompression of an entire volume.

Per-volume encryption

Does the filesystem support real-time transparent encryption and decryption of an entire volume.

Per-file compression

Does the filesystem support real-time transparent compression and decompression of individual files.

Per-file encryption

Does the filesystem support real-time transparent encryption and decryption of individual files.

Access control lists

Does the filesystem support multi-user access control lists (ACLs).
