Powershell – Age of File Report – Local or Remote

Here’s a very quick post by request.I just had a request for searching the file system for files matching certain criteria such as file age based on the date created. The function Get-FileAgingReport uses get-childitem cmdlet. This function uses two mandatory input parameters Computername and Folder Path.The function is validated for computer connectivity and folder existence. Invalid entries will throw proper message for better handling.
The output can be your powershell console/ISE or you can redirect it to a file.

Valid function call:-

ps:\>Get-FileAgingReport -Computername aqdata18 -FolderFullPath f:\powersql |Out-File c:\FileAge.txt

ps:\>Get-FileAgingReport -Computername aqdata18 -FolderFullPath f:\powersql

Image

Function Call :- Invalid Computername

ps:\>Get-FileAgingReport -Computername dbinst18 -FolderFullPath f:\powersql

Function Call :- Invalid FolderPath

ps:\>Get-FileAgingReport -Computername abcdef -FolderFullPath c:\powers

Code:-

Function Get-FileAgingReport { 
Param( 
[Parameter(Mandatory=$true)] 
[string[]]$Computername, 
[Parameter(Mandatory=$true)] 
[String]$FolderFullPath) 
$Object =@() 

FUNCTION getUNCPath($infile) 
{ 
$qualifier = Split-Path $infile -qualifier  
$drive = $qualifier.substring(0,1)  
$noqualifier = Split-Path $infile -noQualifier  
“$drive`$$noqualifier” 
} 
if (!(Test-Connection -ComputerName $Computername -Count 1 -Quiet))
