Answer Key

OS function: managing files

Section A: Quick Questions

A — The OS keeps track of files and folders and records where each file is stored

B — Moving the file

A — Copying the file

A — A folder called Homework containing a subfolder called Maths

B — Report.docx and Report_v2.docx

Section B: Match the Pairs

copy report.docx D:\Backup\ → The OS makes a duplicate of the file in a new folder while the original stays where it is

del C:\Homework\old_notes.txt → The OS removes the file from its folder so the user can no longer open it from that location

A folder structure organises files in a hierarchy, with folders placed inside other folders → C:\School\Science\Biology\cells.docx

File permissions control who can read or write a file, and the OS enforces them → report.docx: user = read and write, guest = read only

move photo.jpg D:\Pictures\ (the original photo.jpg is still in the old folder) → Moving a file takes it out of the old folder, so the original should not remain. Leaving it behind describes copying, not moving.

Two files in the same folder are both named essay.docx → Two files in the same folder cannot share a name because the OS would not know which file is being asked for.

Section C: Definitions

file management — An OS function that keeps track of files and folders, lets users create, name, open, copy, move and delete them, and records where each file is stored.

Section D: Fill in the Blanks

mkdir homework

cp report.txt backup/

mv report.txt archive/

rm old_notes.txt

chmod -w report.txt

Section E: Spot the Error

A — rm deletes files and folders. To create a new folder the OS needs mkdir Homework, otherwise the later cd Homework fails.

C — mv moves the file, so the original disappears from Documents. To make a copy and keep the original, use cp report.txt backup/.

B — cp copies the file and leaves the original where it was. Moving a file needs mv photo.jpg Pictures/.

D — The space makes the OS read two file names, draft and old.txt. The file name must be written as one name: draft_old.txt.

B — +w adds write permission, so users could still change the file. To make it read only, remove write permission with chmod -w notes.txt.
