Every file or directory is represented by an inode. The term "inode" comes from "index node" (over time, it became i-node and then inode). [25] The inode includes data about the size, permission, ownership, and location on disk of the file or directory. Example of ext2 inode structure:
ISO 9660 traces its roots to the High Sierra Format, [2] which arranged file information in a dense, sequential layout to minimize nonsequential access by using a hierarchical (eight levels of directories deep) tree file system arrangement, similar to UNIX and FAT. To facilitate cross platform compatibility, it defined a minimal set of common ...

Such directories are optional, but if they exist, they have some requirements. /media: Mount points for removable media such as CD-ROMs (appeared in FHS-2.3 in 2004). /mnt: Temporarily mounted filesystems. /opt: Add-on application software packages. [7] /proc: Virtual filesystem providing process and kernel information as files. In Linux ...
(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.
ext4 (fourth extended filesystem) is a journaling file system for Linux, developed as the successor to ext3.. ext4 was initially a series of backward-compatible extensions to ext3, many of them originally developed by Cluster File Systems for the Lustre file system between 2003 and 2006, meant to extend storage limits and add other performance improvements.

Linux, macOS, Windows Genozip, a compressor for genomic file formats such as FASTQ, BAM, VCF and others. [4].gz application/gzip [5] gzip: Unix-like GNU Zip, the primary compression format used by Unix-like systems. The compression algorithm is Deflate, which combines LZSS with Huffman coding. .lz application/x-lzip lzip: Unix-like
It is a clone of SGI's fsn file manager for IRIX systems, aimed to run on modern Linux and other Unix-like operating systems. [1] It is capable of representing file systems in two ways: MapV mode: files and directories are represented as cuboids of equal height, with the size of the cuboid representing the size of the file or directory.
