The SpartaDOS File System
The proprietary file system format, called SpartaDOS FS, (unrelated to and not compatible with MS-DOS FAT) offers full support for subdirectories, MS-DOS-like attributes (AHPS: Archived, Hidden, Protected, Subdirectory), modification date and time stamps, random access to data within a file, sparse files.
The file naming convenience is 8+3 (this scheme, inherited from CP/M, is normal on Atari). The directory structure is hierarchical, there are no other than practical limits in nesting directories. A directory can contain up to 1423 entries of files and other directories.
The file system is 16-bit: a drive can contain up to 65535 logical sectors (sector 0 does not exist on Atari disks). The logical sector size is 128 or 256 bytes in earlier versions, and 128, 256 and 512 bytes as of v. 4.40. This makes a maximum capacity of 16 MB per partition in earlier versions, and 32 MB as of v.4.40. A 4 GB per disk - by making sector clusters, up to 65536 bytes per cluster - is theoretically possible, but not yet implemented.

Famous quotes containing the words file and/or system:
“I have been a soreheaded occupant of a file drawer labeled “Science Fiction” ... and I would like out, particularly since so many serious critics regularly mistake the drawer for a urinal.”
—Kurt Vonnegut, Jr. (b. 1922)
“Few white citizens are acquainted with blacks other than those projected by the media and the so—called educational system, which is nothing more than a system of rewards and punishments based upon one’s ability to pledge loyalty oaths to Anglo culture. The media and the “educational system” are the prime sources of racism in the United States.”
—Ishmael Reed (b. 1938)
