What is LTFS?
LTFS (Linear Tape File System) is an open, self-describing tape format supported on LTO-5 and later. It divides the tape into two partitions — a small index partition and a large data partition — so a cartridge can be mounted and browsed like a USB drive. Files can be dragged and dropped in Finder or File Explorer without proprietary backup software.
Why use LTFS?
- Portable — any LTFS-capable system can read the tape, regardless of the software that wrote it.
- Self-describing — the index travels with the data, so archives remain readable for decades.
- Simple — familiar file and folder access for non-specialist users.
- Ideal for media & research — move multi-terabyte projects between studios, labs and partners.
LTFS compatibility
LTFS is supported on LTO-5, LTO-6, LTO-7, LTO-8, LTO-9 and LTO-10 drives and media. Drive vendors provide free LTFS software for Windows, macOS and Linux, and many archive applications write LTFS natively. See our LTO tape drives and LTO tapes.
