This episode explores the filesystems used by various operating systems, each with its own capabilities and use cases. We begin with NTFS, the default for Windows, explaining its support for file permissions, compression, encryption, and large volume sizes. Then we cover exFAT, which bridges compatibility between Windows and macOS, and is commonly used on USB drives and SD cards for its broad device support.

Next, we introduce ext4, the most widely used filesystem for Linux, known for journaled integrity and robust performance on large volumes. Finally, we examine APFS—Apple’s proprietary file system designed for speed, snapshots, and space efficiency on macOS and iOS devices. Understanding these formats is crucial for recognizing compatibility issues, formatting needs, and file recovery scenarios on the A Plus exam. Brought to you by BareMetalCyber.com.
