Mini Lesson

Imagine you spend an hour typing a story and then the power goes out — and you lose everything. That is why saving is one of the most important habits in computing. When you save a file, you create a permanent copy that stays on the device even when it is turned off.

Why saving matters

  • Anything you type lives only in the computer’s temporary memory (RAM) until you save it.
  • If the device is turned off, loses power, or crashes before you save, your work disappears.
  • Saving writes your work to the permanent storage (hard drive or SSD) so it is there next time.
  • Golden rule: save early and save often — every few minutes, not just at the end.

Two ways to save

  • Method 1 — File menu: click File in the top-left menu bar, then click Save. The first time you save a new file, a dialog box will ask you to name it and choose where to save it.
  • Method 2 — Keyboard shortcut: hold Ctrl and press S at the same time. This is faster — use it constantly while working. On a Mac, the shortcut is Cmd + S.

Naming your file

  • Give files a clear, descriptive name so you can find them easily later.
  • Good name: MyStory-Sam-April2026
  • Bad name: untitled or document1
  • Avoid spaces in file names — use hyphens or underscores instead.

Closing a file safely

  • Always save before closing. If you try to close without saving, most programs will ask "Do you want to save?" — always click Yes or Save.
  • Do not just turn off the device — close apps first.

Reopening a saved file

  • Open the Documents folder (or wherever you saved it).
  • Double-click the file icon to open it. It will open in the same program that created it.
  • Or use File to Open Recent inside the program for quick access.
