Linear Tape File System (LTFS) is a self-describing magnetic tape format that defines the organization of data on the tape. Supporting LTO-5 and later LTO generations, data tapes written in the LTFS allow for direct access to file content data and file metadata. Accessing LTFS formatted tapes is similar to accessing files stored on other storage media like disk or removable flash drives. This format presents a standard file system view of the data stored on the tape media, allowing for users to access the data directly from tape.

LTFS Partitions on a Tape


After a cartridge is loaded, the drive quickly reads the index and metadata partition on the tape without having to scan the entire tape. This allows for faster and more efficient access to the data stored on the tape.

Key Highlights of LTFS

  • Access and manage tape files easily
  • Drag-and-drop files to and from tape without device-specific software
  • Share data across platforms
  • Available on LTO-5, LTO-6, LTO-7 and 3592 tapes
