In which scenario would you most likely encounter ext4?

The ext4 file system is a widely used journaling file system in Linux. It is the fourth extended filesystem, which provides improved performance, reliability, and features over its predecessors. Linux distributions commonly use ext4 as their default file system due to its efficient handling of large files, improved speed, and robust capabilities for data recovery and integrity.

Using ext4 with Linux allows users to leverage several advanced features such as support for larger file sizes and volume sizes, extents for file storage, and better performance in terms of speed and fragmentation. It is optimized for the needs of Linux operating environments, making it the most likely scenario in which one would encounter ext4.

In contrast, macOS and Windows OS typically use their own file systems—APFS (Apple File System) for macOS and NTFS (New Technology File System) for Windows—making it unlikely for users on these systems to work with ext4. Shared drives in a network might contain a variety of file systems but are less likely to specifically use ext4 unless they are hosting Linux-based file servers.
