Summary of "Linux Mint 21.1 - Cinnamon...tips for seniors on Nemo the file manager"

The video is a detailed tutorial and guide aimed at senior users on how to effectively use the Nemo file manager in Linux Mint 21.1 with the Cinnamon desktop environment. The presenter focuses on simplifying Linux concepts and taking time to explain features clearly, targeting an audience that prefers slower, more thorough explanations.

Key Technological Concepts and Features Covered:

Linux Mint 21.1 Overview
- Introduction to Linux Mint 21.1 Cinnamon desktop.
- Use of neofetch command to display system info.
Nemo file manager Basics and Tips
- Default settings use double-click; single-click can cause issues with some features.
- Toolbar customization, including showing thumbnails.
- Icon resizing methods:
  - Dragging a slider.
  - Using View menu zoom in/out.
  - Preferred method: holding Control key + scrolling mouse wheel (left hand on keyboard, right hand on mouse) for quick resizing.
- Nemo remembers icon sizes per folder, a useful personalization feature.
File and Folder Management
- Home folder structure, favorites (starred items), hidden files/folders (dot-prefixed).
- Viewing hidden files: right-click or Ctrl+H toggle.
- Creating folders and text documents (not word-processed files).
- File extensions matter for cross-platform compatibility, e.g., Windows and macOS prefer files with extensions.
Image and Wallpaper Handling
- Preview images by selecting and pressing spacebar (quick preview).
- Preview window has resizable thumbnails, no close button (spacebar toggles).
- Right-click to set images as desktop wallpaper; Linux Mint auto-resizes wallpapers.
- Viewing image metadata (e.g., camera model, date).
Mouse Pointer (Cursor) Customization
- Mouse pointers stored in ~/.icons folder for local user or /usr/share/icons for system-wide (root permissions required).
- Adding/removing mouse pointers easily by managing folders in .icons.
- Recommended website for additional pointers: gnome-look.org.
File Transfer and Copy/Move Operations
- Devices shown in Nemo include internal hard drives, external drives, USB sticks (with distinct icons for spinning HDD, SSD, NVMe).
- Copy vs Move distinction:
  - Dragging files/folders to a device (USB/external) performs a copy.
  - Dragging within same device/folder structure performs a move.
- Using split pane (extra pane) feature in Nemo to simplify drag-and-drop between folders/devices.
- Alternative method: opening two separate Nemo windows for file transfer.
File Compression and Extraction
- Multi-select files/folders for compression via right-click.
- Compression formats available: .zip, .7z (modern, supports encryption), and others.
- Default compression location is current folder to avoid losing files.
- Ability to open compressed archives and extract selectively or fully.
- Preview files inside compressed archives without extracting.
Drive and File System Information
- Nemo shows free space on drives at the bottom.
- Right-click properties shows file system type and other metadata.
- Explanation of file system types: NTFS (Windows), ext4 (Linux).
- Using the Disks utility to view detailed drive info and partitions.
- Transfer speed differences: NVMe > SSD > spinning HDD > USB stick (USB transfers much slower).
