What is the output of this Remove-Item command?

Consider a folder named 'TestFolder' containing files 'a.txt' and 'b.txt'. What happens after running this command?

Remove-Item -Path 'TestFolder\a.txt'

PowerShell

Remove-Item -Path 'TestFolder\a.txt'

A Only 'a.txt' is deleted; 'b.txt' remains in 'TestFolder'.

B Both 'a.txt' and 'b.txt' are deleted from 'TestFolder'.

C An error occurs because the folder path is incomplete.

D 'TestFolder' and all its contents are deleted.

💡 Hint

Remove-Item deletes the specified file or folder, not siblings unless specified.

Remove-Item with a file path deletes only that file. It does not affect other files in the folder.

💻 Command Output

intermediate

What error does this Remove-Item command raise?

What error occurs when running this command if 'NonExistentFile.txt' does not exist?

Remove-Item -Path 'NonExistentFile.txt'

PowerShell

Remove-Item -Path 'NonExistentFile.txt'

A AccessDeniedException error.

B No error; command silently succeeds.

C FileNotFoundException error.

D Remove-Item: Cannot find path 'NonExistentFile.txt' because it does not exist.

💡 Hint

By default, Remove-Item throws an error if the path is missing.

Remove-Item throws a terminating error if the specified path does not exist unless -ErrorAction is used.

📝 Syntax

advanced

Which Remove-Item command correctly deletes all files in a folder but keeps the folder?

You want to delete all files inside 'Logs' folder but keep the folder itself. Which command does this correctly?

A Remove-Item -Path 'Logs\*' -Force

B Remove-Item -Path 'Logs\*' -Recurse

C Remove-Item -Path 'Logs' -Recurse

D Remove-Item -Path 'Logs' -Force

💡 Hint

Use wildcard to target contents, not folder itself.

Using 'Logs\*' targets all contents inside 'Logs' folder. -Recurse deletes files and subfolders inside, but not the folder itself.

🚀 Application

How to safely delete a folder and all its contents without prompt?

You want to delete 'OldData' folder and everything inside it without any confirmation prompts. Which command achieves this?

A Remove-Item -Path 'OldData' -Force

B Remove-Item -Path 'OldData' -Confirm:$false

C Remove-Item -Path 'OldData' -Recurse -Force

D Remove-Item -Path 'OldData' -Recurse

💡 Hint

Use parameters to suppress prompts and delete recursively.

-Recurse deletes all contents including subfolders. -Force suppresses prompts and deletes read-only files.

🧠 Conceptual

expert

What is the effect of running Remove-Item with -WhatIf parameter?

You run:

Remove-Item -Path 'Data\*' -Recurse -WhatIf

What happens?

A It shows what would be deleted without actually deleting anything.

B It causes a syntax error because -WhatIf cannot be combined with -Recurse.

C It deletes files silently without any output.

D It deletes the files and shows a confirmation prompt.

💡 Hint

-WhatIf is a safety feature to preview actions.

-WhatIf simulates the command and shows what would happen without making changes.
