The Linear Tape File System (LTFS) is a file system that allows files stored on magnetic tape to be accessed in a similar fashion to those on disk or removable flash drives. It requires both a specific format of data on the tape media and software to provide a file system interface to the data.
Since LTFS is an open standard, LTFS-formatted tapes are usable by a wide variety of computing systems. The block structure of the tape is logical so interblock gaps, file marks, tape marks and so forth take only a few bytes each. In LTO-1 and LTO-2, this logical structure has CRC codes and compression added to create blocks of 403,884 bytes.
The IBM Ultrium 6 technology is designed to support media partitioning, IBM Linear Tape File System (LTFS) technology and encryption of data and WORM cartridges. [ 41 ] TS2260 – Half-height external standalone or rack mountable shelf unit with a native physical capacity of 2.5 TB.
Linear Tape File System: Allows files stored on magnetic tape to be accessed in a similar fashion to those on disk or removable flash drives. NTFS-3G and Captive NTFS, allowing access to NTFS filesystems. retro-fuse: retro-fuse is a user-space filesystem that provides a way to mount filesystems created by ancient Unix systems on modern OSes.
The IBM implementation of this file system has been released as the open-source IBM Linear Tape File System — Single Drive Edition (LTFS-SDE) product. The Linear Tape File System uses a separate partition on the tape to record the index meta-data, thereby avoiding the problems associated with scattering directory entries across the entire tape.
The often-used compression factor of 2:1 is optimistic and generally only achievable for text data; a more realistic factor for a file system is 1.3:1 to 1.5:1, although drive compression applied to pre-compressed data can actually make the written data larger than having compression turned off in the tape drive.
In computing, a file shortcut is a handle in a user interface that allows the user to find a file or resource located in a different directory or folder from the place where the shortcut is located. Similarly, an Internet shortcut allows the user to open a page, file or resource located at a remote Internet location or Web site.
The program can accomplish file management tasks with a few keystrokes, and mouse input is optional. In conjunction with extensions including the rifle file opener and scope.sh, ranger can be scripted to open files with pre-defined programs, and to display a preview of the selected file by calling external programs.
