Powershell: Expand-Archive does not honor -Confirm:$false

[ChrisLynchHPE]

Steps to reproduce

Using the following command will prompt you to confirm the creation of sub-directories if they exist within the ZIP (like a Hyper-V VM template in ZPI form)

$Path = "C:\Mydirectory\archive.zip"
Expand-Archive -Path $Path -DestinationPath $env:TEMP\MyTempDirectory -Confirm:$false                                                                                                                      

Expected behavior

When using Expand-Archive, the Cmdlet should honor the use of -Confirm:$false, especially when creating directories that do not exist.

Actual behavior

When passing the -Confirm:$False parameter, the user is prompted for confirmation to create the destination directory, or any embedded child directory within the ZIP archive.

$Path = "C:\Mydirectory\archive.zip"
Expand-Archive -Path $Path -DestinationPath $env:TEMP\MyTempDirectory -Confirm:$false 
Unzipping C:\Mydirectory\archive.zip                                    
Confirm

Docs says that -Force suppresses confirmation.

[vexx32]

Yep, another command that chose to use -Force instead of a common parameter for prompts. Makes you wonder why they even bothered to implement ShouldProcessing. 😔

[ChrisLynchHPE]

Except -Force doesn't work either. I tried that. Same result.

@ChrisLynchHPE not to be bunting you all over the place, but as far as I recall the *-Archive cmdlets aren't managed in this repo; I think they live in the Microsoft.PowerShell.Archive repo; you'd need to file the issue there.

With any luck, @romero126 might be able to sneak that fix in before / after he gets his major work sorted out there, assuming there's still interest in developing that module further...

[romero126]

I believe that whole Function is planned to get an overhaul soon.

Which would be better use of cycles? Fix a bug or release a future facing feature?

Im actually curious.

Also This bug should be in Microsoft.Powershell.Archive repository.

I ask MSFT team without answer https://github.com/PowerShell/Microsoft.PowerShell.Archive/issues/19#issuecomment-610500841

This issue has been marked as answered and has not had any activity for 1 day. It has been closed for housekeeping purposes.

@romero126 Sorry for the late reply here. If working on a new feature to this Cmdlet fixes the issue, to me it doesn't matter. As long as it is fixed.
