If you want, I can also create:

✅ YouTube Shorts titles for each directory (/bin, /etc, /home, etc.)

✅ A Linux File System quiz to match this video

✅ A thumbnail text suggestion for higher CTR

Just tell me 👍

can you create thumbnail for this

Yes 👍 I can help you design the thumbnail concept (text, layout, colors, and elements) so you or a designer can easily create it in Canva / Photoshop / Figma.
Below is a high-CTR YouTube thumbnail blueprint specifically for your Linux File System video.

🎨 Thumbnail Concept (Recommended)
🖼️ Main Thumbnail Text (BIG & BOLD)

Use one of these (max 4–5 words):

Option 1 (Best for Beginners):

LINUX FILE SYSTEM

Option 2 (More Catchy):

LINUX DIRECTORIES EXPLAINED

Option 3 (Technical Audience):

LINUX FILE SYSTEM HIERARCHY

🧩 Supporting Text (Smaller, Optional)

Place in a corner or below main text:

/bin /etc /home /boot

or

/ /bin /etc /home

🐧 Visual Elements to Include

🐧 Linux Tux logo (left or right side)

📁 Folder icons stacked or tree-style

🌳 A simple directory tree graphic

/
