Operating System and File Management
This domain covers Windows desktop operations and file management: icons, Start menu, taskbar, windows, files and folders, extensions, selecting, copying, moving, deleting, Recycle Bin, and search. The exam tests practical command knowledge and path/extension recognition.
Core rules
- An operating system manages hardware, runs applications, and provides a user interface. Windows is a GUI OS; its desktop contains icons, the taskbar, and the notification area.
- A file name has a name and an extension. Common extensions: .docx (Word), .xlsx (Excel), .pptx (PowerPoint), .txt (text), .jpg/.png (image), .mp3 (audio), .exe (program).
- Windows file names cannot contain \ / : * ? " < > |. Keep names short and descriptive.
- Ctrl+C copies, Ctrl+X cuts, Ctrl+V pastes. Ctrl+Z undoes; Ctrl+A selects all. Shift+click selects a continuous range; Ctrl+click selects non-adjacent items.
- Deleting to the Recycle Bin is reversible; Shift+Delete bypasses it. Files deleted from a pen drive or network drive usually do not go to the Recycle Bin.
Worked example
A student has C:\School\Notes.docx and wants a copy on a pen drive (E:). Select the file, press Ctrl+C, open E:, press Ctrl+V. Reasoning: copying leaves the original in place; cutting (Ctrl+X) would remove it from C: after paste. If the same file is dragged from C: to E:, Windows copies by default because the drives differ; dragging within the same drive moves it. Check the new path E:\Notes.docx to confirm success.
Traps that cost marks
- Thinking Enter renames a file; F2 is the rename key.
- Confusing moving and copying when dragging between drives.
- Believing every deleted file is recoverable from the Recycle Bin.
- Ignoring the extension and assuming a file's contents from its icon.
- Using * and ? incorrectly: * stands for any number of characters, ? for exactly one.
