Windows Power Shell Script to Find Full File Path Length for all files in Directory

In some cases, we may need to identify the maximum length of full file path in a directory such that we can reduce the file name to avoid file length/security policy issues.

PS Script:-

$pathToScan = "C:\temp\File_Length"  
$outputFilePath = "C:\temp\File_Length\output.txt" 
$writeOnConsole = $true   

$outputDir = Split-Path $outputFilePath -Parent
if (!(Test-Path $outputDir)) { New-Item $outputDir -ItemType Directory }

if ($writeOnConsole) {Write-Host "*************************************"}
if ($writeOnConsole) {Write-Host "  List of files with file Length :-  "}
if ($writeOnConsole) {Write-Host "*************************************"}
$stream = New-Object System.IO.StreamWriter($outputFilePath, $false)
Get-ChildItem -Path $pathToScan -Recurse -Force | Sort-Object {($_.FullName.Length)} -Descending | ForEach-Object {
    $Path = $_.FullName
    $len = $_.FullName.Length
    $strg = "$len : $Path"
    
    if ($writeOnConsole) { Write-Host $strg }

    $stream.WriteLine($strg)
}
$stream.Close()

Output:-

Windows Power Shell script to Purge/Cleanup Backup & Transaction files

At times, we need to purge backup files (.bak, *.trn) which are older than some x days from the server on the regular basis, such that Disk Space and SQL Data backups will be maintained consistently within the server.

Power Shell Script:-

The below power shell script will purge the backup files (which are older than 5 days) from server, this script identifies the older files based on the last modified date time.

Based on your requirement, you can change the date range and schedule this script for Server Maintenance.

Get-ChildItem -Path "C:\Backups" -Recurse -ErrorAction SilentlyContinue -include *.bak, *.trn | 
Where-Object {$_.LastWriteTime -lt (Get-Date).AddDays(-5) -and $_.PSIsContainer -eq $False} | 
Remove-Item

Using Windows Power Shell to get the Server Disk Space Information

To find Drive Names, Total Space, Free Space and Free Space Percentage for the list of Servers specified in computers.txt file using Power Shell Script.

Prerequisites:-

  1. Save the computers.txt file and below PS script in the same folder
  2. User should have access to the servers mentioned in computers.txt file
  3. There should not be any empty space or new line without Servername in computers.txt file

PS Script:-

$path=Split-Path $MyInvocation.MyCommand.path 
$Computers = get-content "$path\computers.txt" 
foreach ($Computer in $Computers)  
{  
$Disks = Get-wmiobject  Win32_LogicalDisk -computername $Computer -ErrorAction SilentlyContinue -filter "DriveType= 3" 
$Servername = (Get-wmiobject  CIM_ComputerSystem -ComputerName $computer).Name
foreach ($objdisk in $Disks)  
{  
        
    $total=“{0:N3}” -f ($objDisk.Size/1GB)  
    $free= “{0:N3}” -f ($objDisk.FreeSpace/1GB)  
    $freePercent="{0:P2}" -f ([double]$objDisk.FreeSpace/[double]$objDisk.Size)  
       
       Write-Host "Servername      :" $Servername  
       Write-Host "Drive Folder    :" $objDisk.DeviceID "Drive" 
       Write-Host "Total size (GB) :" $total 
       Write-Host "Free Space (GB) :" $free 
       Write-Host “Free Space (%)  :” $freePercent 
} 
}

Output:-

To save the Output to Diskspace_Report.csv file, Use below PS script:-

$path=Split-Path $MyInvocation.MyCommand.path 
$Computers = get-content "$path\computers.txt" 
foreach ($Computer in $Computers)  
{  
$Disks = Get-wmiobject  Win32_LogicalDisk -computername $Computer -ErrorAction SilentlyContinue -filter "DriveType= 3" 
$Servername = (Get-wmiobject  CIM_ComputerSystem -ComputerName $computer).Name
foreach ($objdisk in $Disks)  
{  
        
    $total=“{0:N3}” -f ($objDisk.Size/1GB)  
    $free= “{0:N3}” -f ($objDisk.FreeSpace/1GB)  
    $freePercent="{0:P2}" -f ([double]$objDisk.FreeSpace/[double]$objDisk.Size)  

        $out=New-Object PSObject 
        $out | Add-Member -MemberType NoteProperty -Name "Servername" -Value $Servername 
        $out | Add-Member -MemberType NoteProperty -Name "Drive" -Value $objDisk.DeviceID  
        $out | Add-Member -MemberType NoteProperty -Name "Total size (GB)" -Value $total 
        $out | Add-Member -MemberType NoteProperty -Name “Free Space (GB)” -Value $free 
        $out | Add-Member -MemberType NoteProperty -Name “Free Space (%)” -Value $freePercent 
        $out | Add-Member -MemberType NoteProperty -Name "Name " -Value $objdisk.volumename 
        $out | Add-Member -MemberType NoteProperty -Name "DriveType" -Value $objdisk.DriveType 
        $out | export-csv $path\Diskspace_Report.csv -NoTypeInformation -Append   
}
