Understanding files and folders

~26s

A file is a single document, photo, or piece of information (e.g. "Invoice March 2025.pdf"). A folder is a container that holds files — like a physical folder in a filing cabinet. Your computer has a built-in file manager: File Explorer on Windows (the yellow folder icon on your taskbar) and Finder on Mac (the blue/white smiley face in your Dock).

Quick Tip

Think of your computer like a filing cabinet. Documents go in Documents, photos in Pictures, downloads in Downloads.

Finding a lost file

~31s

On Windows: click the search bar at the bottom of the screen (or press the Windows key and start typing). Type part of the file name — Windows will find it. On Mac: press Command + Space to open Spotlight search and type the file name. If you only remember roughly when you created or downloaded it, sort your Downloads folder by date — newest files appear at the top.

Quick Tip

Can't remember the name? Search for the file type instead — try searching ".pdf" to find all PDFs, or type a word you remember from inside the document.

Renaming files so you can find them later

~26s

Vague file names like "Document1.docx" are impossible to find later. Right-click (Windows) or Control-click (Mac) any file and choose "Rename." Type a clear, descriptive name like "2025 Tax Return - HMRC.pdf" or "Mum's Birthday Party Photos June 2025." Press Enter to save. Include the year in file names — your future self will thank you.

Quick Tip

Avoid using /, \, :, * or ? in file names — these are reserved by your computer and can cause errors.

Moving and copying files

~18s

To move a file: click and drag it into the folder you want, or right-click → "Cut" → open the destination folder → right-click → "Paste." To copy (keeping the original): right-click → "Copy" → open the destination → right-click → "Paste." On Mac, drag to move. To copy on Mac, hold Option while dragging.

Creating a sensible folder structure

~21s

A simple structure beats a complicated one. Try: DocumentsFinance (bills, tax, bank), Health (prescriptions, appointment letters), Family, Work. Inside Finance, create yearly subfolders: Finance → 2024, Finance → 2025. Right-click inside any folder and select "New Folder" to create one. Name it and press Enter.

Quick Tip

You don't need dozens of folders. Five or six top-level folders cover most people's needs.

Deleting files and emptying the bin

~34s

To delete a file: select it and press the Delete key (Windows) or drag it to the Bin/Trash on Mac. Deleted files go to the Recycle Bin (Windows) or Bin (Mac) — they're not gone yet. To permanently delete and free up space: right-click the Recycle Bin/Bin icon on your desktop and choose "Empty Recycle Bin" or "Empty Bin." Do this every few months.

Quick Tip

Press Ctrl+Z (Windows) or ⌘+Z (Mac) immediately after an accidental delete to undo it — before you empty the bin.

Warning

Once you empty the bin, files are permanently deleted and cannot be recovered (unless you have a backup). Double-check before emptying.
