In GNU/Linux, I can just do this:
tar cfz hierarchy.tgz hierarchy
and it just works, even if some of the items in hierarchy are being used by other processes.
In Windows, I can right-click on a folder and send it to a compressed zip file, so long as it's in another place, like the Desktop, and that works.
But in Windows PowerShell, something you would think would be so simple, isn't:
PS E:\> Compress-Archive -Path e:\lib -DestinationPath .\e-lib-all.zip
ZipArchiveHelper : The process cannot access the file
'E:\lib\company\data\data-azure-java\1.0.1\data-azure-java-1.0.1.jar' because it is being used by another process.

I asked a coworker, what's the PowerShell equivalent of the GUI way that just works? He thought what the GUI does in the background is create a copy using service level rather than user permissions, and then zips that.
Is there a PowerShell way to do this? I've tried some other things that did not work, namely:
Copy-Item -Path "E:\lib" -Force -PassThru | `
Get-ChildItem | `
Compress-Archive -DestinationPath "E:\e-lib-all.zip"
Get-ChildItem -Recurse -Path $sourcePath | Compress-Archive -DestinationPath $destinationPath
Get-ChildItem -Recurse -Path "E:\lib" | Compress-Archive -DestinationPath "E:\e-lib-all.zip"
Yes, I looked at previous SO post Compress-Archive error: PermissionDenied but it didn't help (I got the same errors).
