However, not all file systems on those systems are case-sensitive; by default, HFS+ and APFS in macOS are case-insensitive but case-preserving, and SMB servers usually provide case-insensitive behavior (even when the underlying file system is case-sensitive, e.g. Samba on most Unix-like systems), and SMB client file systems provide case ...

File names: Traditionally, Unix-like operating systems treat file names case-sensitively while Microsoft Windows is case-insensitive but, for most file systems, case-preserving. For more details, see below. Variable names: Some programming languages are case-sensitive for their variable names while others are not. For more details, see below.
Some file systems match file names as case sensitive and others as case insensitive. For example, the names MYFILE and myfile match the same file for case insensitive, but different files for case sensitive. Most modern file systems allow a file name to contain a wide range of characters from the Unicode character set. Some restrict characters ...
A system that is non-case-preserving is necessarily also case-insensitive. This applies, for example, to Identifiers (column and table names) in some relational databases (for example DB2, Interbase/Firebird, Oracle and Snowflake [1]), unless the identifier is specified within double quotation marks (in which case the identifier becomes case-sensitive).
Shared-disk file systems (also called shared-storage file systems, SAN file system, Clustered file system or even cluster file systems) are primarily used in a storage area network where all nodes directly access the block storage where the file system is located. This makes it possible for nodes to fail without affecting access to the file ...
The original Unix file system supported three types of files: ordinary files, directories, and "special files", also termed device files. [1] The Berkeley Software Distribution (BSD) and System V each added a file type to be used for interprocess communication: BSD added sockets, [3] while System V added FIFO files.
Early Unix filesystems were referred to simply as FS.FS only included the boot block, superblock, a clump of inodes, and the data blocks.This worked well for the small disks early Unixes were designed for, but as technology advanced and disks grew larger, moving the head back and forth between the clump of inodes and the data blocks they referred to caused thrashing.
