A full file reference (pathname in today's parlance) consists of a filename, a filetype, and a disk letter called a filemode (e.g. A or B ). Minidisks can correspond to physical disk drives, but more typically refer to logical drives, which are mapped automatically onto shared devices by the operating system as sets of virtual cylinders .
Each file or directory stored within it is represented by a 32-byte entry in the table. Each entry records the name, extension, attributes (archive, directory, hidden, read-only, system and volume), the date and time of creation, the address of the first cluster of the file/directory's data and finally the size of the file/directory.
A filename is a string used to uniquely identify a file stored on this structure. Before the advent of 32-bit operating systems, file names were typically limited to short names (6 to 14 characters in size).
Joliet allows Unicode characters to be used for all text fields, which includes file names and the volume name. A "Secondary" volume descriptor with type 2 contains the same information as the Primary one (sector 16 offset 40 bytes), but in UCS-2BE in sector 17, offset 40 bytes. As a result of this, the volume name is limited to 16 characters.
(System) Snapshot: When set, indicates that the file or directory is a snapshot file. This attribute is maintained by the system, and cannot be set, even by the super-user. whereas DragonFly BSD supports: [14] (User and System) No-history: When set, indicates that history should not be retained for the file or directory.
This path points to a file with the name File.txt, located in the directory Temp, which in turn is located in the root directory of the drive A:. C:..\File.txt This path refers to a file called File.txt located in the parent directory of the current directory on drive C:. Folder\SubFolder\File.txt
In the FAT filesystem, the volume label was traditionally restricted to 11 characters (reflecting the 8.3 restrictions, but not divided into name and extension fields) even when long file name was enabled, stored as an entry within a disk's root directory with a special volume-label attribute bit set, and also copied to an 11-byte field within ...
It helps users organize files, photos and other documents on their local drives. File management and data associations occur by labeling files with tags. Tags may vary in color and may also differ in purpose. Users create, name, edit, sort, group, rename and delete their own tags by following their own logic in the file-tagging process.
