Files and Storage
Files and Storage
Use Files and Storage when you need confidence with file operations, storage layout, and safer changes to disks and mounted devices.
This domain is public-ready across Learning, Practice, Troubleshooting, and Reference.
What you will learn
- Read, create, search, copy, move, and delete with confidence
- Distinguish files, folders, paths, partitions, and mounted storage
- Inspect before changing storage so destructive mistakes stay rare
Coverage in this domain
Best when you need real confidence with files, paths, disks, and storage changes.

Lesson 1 File System
File System Architecture: How Your OS Organises Data Understand the map of the file system well enough to recognize Windows drive-letter paths, Linux root-tree paths, and the difference between a file name and the data behind it. Lesson 2 File System
Navigation: GUI First Use the graphical file manager to build a reliable spatial map of paths, hidden files, and frequent locations before translating those actions to the command line. Lesson 3 File System
Navigation: CLI Translation Translate basic GUI navigation into terminal navigation using the current directory, listing commands, absolute and relative paths, and a few high-value movement shortcuts. Lesson 4 File System
File Operations: View and Read Read files safely from the terminal, inspect the beginning or end of long output, and search inside text without opening a GUI editor. Lesson 5 File System
File Operations: Create and Edit Create folders and files from the terminal, write simple text safely, and make small edits without relying on a full GUI workflow. Lesson 6 File System
File Operations: Copy, Move, Delete Copy, move, rename, delete, and archive files safely so you can reorganize work without losing track of what changed. Lesson 7 File System
Search and Find Find programs and files in a way that matches the real problem: command lookup, live recursive search, or fast indexed search. Lesson 8 File System
WSL: The Windows↔Linux Bridge Learn how to access your Windows files from inside Linux, access your Linux files from Windows Explorer, and run commands across both OSs simultaneously. Lesson 9 File System
File System Lab: Mini Scenario Use navigation, reading, creating, moving, searching, and archiving together to clean up a safe practice project from the terminal. Lesson 10 Storage
Storage Architecture Understand how disks, partitions, filesystems, and mount points fit together so storage changes make sense before any formatting or mounting commands are used. Lesson 11 Storage
Disk Management: GUI Use graphical disk tools to inspect disks and partitions safely, and understand which actions are low-risk inspection versus high-risk modification. Lesson 12 Storage
Disk Management: CLI Inspect storage devices and mount points from the command line, and understand which commands are observational versus potentially destructive. Lesson 13 Storage
Storage Lab: External Drive Setup Walk through the storage setup sequence conceptually and in safe practice steps so external-drive preparation makes sense before touching real data. Practice this domain FILE SYSTEM & STORAGE
The Linux File System Tree
Navigate the standard Linux directory tree well enough to predict where configs, logs, programs, and user files usually live.
File System Mastery Inside /etc - The Config VaultInspect common files inside /etc in read-only mode so you can recognize system configuration safely and confidently.
File System Mastery Inside /var - The Living DataInspect /var safely so you can find changing data such as logs and understand how to read it without making the situation worse.
File System Mastery Inside /proc and /sys - The Virtual WindowsRead basic live system information from /proc and /sys so you understand that Linux exposes many hardware and kernel details as files.

Disk Is Almost Full
Use this when free space is running low and you need to recover space without guessing or deleting the wrong data.
Files and Storage External Drive Does Not AppearUse this when a USB drive or other external storage device is connected but does not show up where the user expects.
Files and Storage File or Folder Seems MissingUse this when a file or folder appears to be gone and you need to separate wrong location, hidden state, sync state, and real deletion.

Task guide Mount an External Drive SafelyInspect an external disk first, then mount it deliberately without confusing the device, partition, filesystem, and mount point layers.
Task guide File System and Path MapUnderstand files, folders, paths, roots, and mounts as one navigable structure instead of isolated commands.
Tree map Storage, Partition, and Mount ModelSee disks, partitions, filesystems, mounts, and external drives as a layered storage model instead of a list of admin tools.
