Question 4. File Directories

In this question, you are given a zip file, which contains some folders and files. You will unzip the given file, manipulate the files and folders, zip the resulting file structure and submit it, along with answers to the questions in this exercise.

First, download and save SSD2 File System.zip onto your Desktop. Then unzip the file.

a. What is the absolute path of the file named test.txt in SSD2 File System folder?

Answer: C:\Documents and Settings\Guest\桌面\SSD2 File System\Temp3\ test.txt

b. How many parent directories does test.txt have?

Answer: 5

c. Create a shortcut of test.txt and place it in the same directory. Rename the shortcut “MyTest”. Copy and paste a screenshot showing the file property of MyTest.

d. Examine the file property of test.txt. Explain why the values for Size and Size on disk are different. What is the term for the difference between the two sizes?

Answer: Shortcuts have names and live in folders just the way files do. But, a shortcut does not actually hold any data. Therefore the values for Size and Size on disk are different.

e. Opening MyTest or test.txt both result in the display of the file. Explain the difference between MyTest and test.txt.

Answer: Shortcuts have names and live in folders just the way files do. But, a shortcut does not actually hold any data. Instead, it has a shortcut property that specifies the path to the file where the data can be found. This file is called the target of the shortcut. The target can be anywhere, even on a different drive. A shortcut only refers to its target; it is not a copy of the target. So, when you open a shortcut and edit what you find there, you are actually editing the target file.

f. What are the different file extensions in folder Temp1?

Answer: .gif .html .xml

g. List the most recently modified item in SSD2 File System folder.

Answer: The most recently modified item is name the shortcut of test.txt of “MyTest”.
