1

Create a new folder named ProjectDocs

Write a PowerShell command using New-Item to create a folder named ProjectDocs in the current directory.

PowerShell

# Use New-Item to create a folder named ProjectDocs
# Your code here

Hint

Use -ItemType Directory to create a folder.

2

Set the folder path in a variable

Create a variable called $folderPath and set it to the path ./ProjectDocs.

PowerShell

New-Item -Path . -Name ProjectDocs -ItemType Directory
# Create a variable $folderPath with value './ProjectDocs'
# Your code here

Hint

Use $folderPath = './ProjectDocs' to store the folder path.

3

Create a new text file README.txt inside ProjectDocs

Use New-Item with -Path set to $folderPath and -Name set to README.txt to create a new file inside the folder.

PowerShell

New-Item -Path . -Name ProjectDocs -ItemType Directory
$folderPath = './ProjectDocs'
# Use New-Item to create README.txt inside $folderPath
# Your code here

Hint

Use -ItemType File to create a file.

4

Display the full path of the created README.txt file

Assign the result of the New-Item command creating README.txt to a variable called $newFile. Then print the full path of the file using Write-Output and $newFile.FullName.

PowerShell

New-Item -Path . -Name ProjectDocs -ItemType Directory
$folderPath = './ProjectDocs'
# Assign the new file creation to $newFile
$newFile = New-Item -Path $folderPath -Name README.txt -ItemType File
# Print the full path of $newFile
# Your code here

Hint

Store the created file in $newFile and print $newFile.FullName.

   The command uses New-Item with -ItemType Directory, which means it will create a folder (directory).

2. Step 2: Analyze the path parameter

   The -Path 'C:\Test' specifies the location and name of the new folder to create on the C drive.

3. Final Answer:
