Episode 42 — Filesystem Concepts: Compression, Encryption, and Types

This episode focuses on filesystem concepts you’ll encounter in the CompTIA IT Fundamentals (ITF+) certification exam, from the basics of directory structures to advanced features like compression and encryption. You’ll learn how filesystems store and organize data, the differences between FAT32, NTFS, ext4, and other formats, and how these affect performance, compatibility, and security.

We’ll also explain how compression saves storage space and how encryption protects sensitive information, along with scenarios where each is most beneficial. This knowledge equips you to identify the right filesystem choices for different needs, both in exam questions and practical IT work. Produced by BareMetalCyber.com.
