Misplaced Pages

This is an old revision of this page, as edited by AlistairMcMillan (talk | contribs) at 11:26, 15 August 2005 (Common Filesystem Features moved to Common filesystem features). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

This is the glossary of the Common Filesystem 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.

Inventor

Here comes the name of who created the filesystem specification, not having to be the first who implemented it in the real world.

Name

Here comes the full, non abbreviated, name of the filesystem itself

Native Operating System

Here comes the name of the first operating system that included an implementation of the filesystem.

Partition identificator

Here comes the partition identificator, along with the partitioning scheme of it.

Bad sector allocation

This describes how the filesystem allocates sectors marked as bad.

File allocation

This describes how the filesystem allocates sectors used by files.

Directory structure

This describes how the subdirectories are implemented.

Namespace

This describes the characters that can be used, or not, for the filenames.

Maximum filename size

This describes the maximum number of characters that the filename can have.

Maximum files

This describes the maximum number of files the filesystem can allocate.

Maximum volume size

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

Dates handled

This describes what type of dates can handle the filesystem. They can be: Creation, Access, Modified or Changed

Creation date

This is the date when the file was created.

Access date

This is the date when the file was last accessed for read.

Modified date

This is the date when the file was last accessed for write, no matter if no write was really made.

Changed date

This is the date when anything related with the file, like attributes, ACLs, filename, etc, is modified.

Maximum date

This describes the maximum year that can be handled by the filesystem, as specification says.

Attributes

This describes the basic file attributes.

Named streams

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

Per-volume compression

This describes if the filesystem supports real-time and transparent compression and decompression of a whole volume.

Per-volume encryption

This describes if the filesystem supports real-time and transparent encryption and decryption of a whole volume.

Per-file compression

This describes if the filesystem supports real-time and transparent compression and decompression of files.

Per-file encryption

This describes if the filesystem supports real-time and transparent encryption and decryption of files.

Access Control Lists

This describes if the filesystem supports multiuser Access Control Lists
