To add the tag to the Azure VM we need to use the Update-AZTag command. This command will merge the new tag to the existing tag(s) of the VM. If you are planning to add the entirely new VM tag, you can use the New-AZTag command.

We will first retrieve the content of the folder using the Get-ChildItem command and then pipeline the Measure-Object command as shown below.Get-ChildItem C:\Temp\ -Recurse | Measure-Object -Property Length -SumOutputCount : 1514 Average : Sum : 372060503 Maximum : Minimum : Property : LengthSo the above output shows that there is a total of 1514 files and folders and the sum shows the size of all the files and folders combined in KB.

To run the PowerShell script from the command prompt, we can use the below command.ExampleFor example, we have a script TestPS.ps1 which first starts the spooler service and then copies a file to a different location. We need to call this script using the command prompt.C:\> PowerShell.exe -command "C:\temp\TestPS.ps1"The above command is similar to running individual PowerShell commands. Here we are providing the path of the script.OutputC:\>PowerShell.exe -command "C:\temp\TestPS.ps1" VERBOSE: Performing the operation "Start-Service" on target "Print Spooler (Spooler)". Status Name DisplayName ------ ----- ---------- Running Spooler Print Spooler VERBOSE: Performing the operation "Copy File" on target "Item: C:\Temp\EnvVariable.txt Destination: ... Read More

If we want to delete the hidden files and folders from the C:\temp on the local computer, we need to use the command shown in this example.ExampleBut first, the below command helps us to retrieve the hidden files and folders from the C:\temp.Get-ChildItem C:\Temp -Hidden -RecurseWe just need to pipe the Remove-Item command and to remove forcibly use -Force parameter.Get-ChildItem C:\Temp -Hidden -Recurse | Remove-Item -Force -VerboseOutput

To delete empty files and folders, we need to first retrieve the list and which has been shown in the earlier articles.ExampleIn this article, we are using the logic that if we find an empty file or folder we will delete them. To implement that logic, use the below script.gci C:\Temp -Recurse | foreach { if($_.Length -eq 0){ Write-Output "Removing Empty File $($_.FullName)" $_.FullName | Remove-Item -Force } if( $_.psiscontainer -eq $true){ if((gci ...

To get the list of empty folder on the windows OS using PowerShell, we can use the below method.gci C:\Temp -Recurse | foreach { if( $_.psiscontainer -eq $true){ if((gci $_.FullName) -eq $null){$_.FullName} } }The above command checks the C:\Temp folder and its subfolders and if the content is empty it returns the Folder full path. The PSISContainer property stands for the folder and GCI is the alias of the Get-ChildItem command. We can alternatively use the below command, instead of using the PSISContainer property.gci C:\Temp -Recurse -Directory | foreach { if((gci $_.FullName) -eq $null){$_.FullName} }

To get the list of empty files in Windows OS using PowerShell, there are two ways, a) Using Length parameter. We will count the length of the file. If it is 0 then the file is empty as shown below.Get-ChildItem C:\Temp\ -Recurse | where{$_.Length -eq 0} | Select @{N='EmptyFiles';E={$_.FullName}}Output:b) Another method is a long one that we don’t want to go into. We need to check each file's content and if it is empty then we will declare that file as an empty file.Get-ChildItem C:\Temp -Recurse -File | foreach{ if((Get-Content $_.FullName) -eq $null){ ...
