Hi guys,

I need your help. I am not able to achive it by myself, I am trying but I am having troubles.

I need to run a script to get the size of a unit and the avilable free space. The same for all units in that server.  I would like to create an .xls with the output

server: server01

c:   20 gb   10 gb free
d:  30 gb    20 gb free
and so for all units

I would like to use WSH and WMI but it is not friendly for me as I would like. I am working hard to learn but I need now.

Could anyone help me?

This script [Powershell] returns CSV file with DeviceID, Size and FreeSize of all local hard drives

Get-WMIObject Win32_LogicalDisk -Filter "DriveType=3" | Select-Object DeviceID,FreeSpace,Size | Export-Csv ./localhdd.csv

Thanks for the reply, It is interesting.

Please, let me explain better.

I would need a powershell such as:

- It will be launch from  my workstation or server of my domain providing administrattors credential in other domains to be able to execute command there.
- The goal is to get:
* To get information about differents hard disk units on target server; total space in disk and free space available. (could have c,d,e,...) units. There is not a rule.
* Export that information to excel, creating the file iin the pc where the scrilpt is being launching (source pc in which I am launching the script). The name of the file is the same that the IP adress of the server where we are connecting to get information.
* In a specific folder on the target server check for files which are  contained into a specific folder and are two weeks old, the goal is delete them (are logs files). report the action in a logs indicating amount of deleted files and the size disk.

Please, I need the help of an expert, It is very important for me to be able to finish this task.

## This scripts generate 2 output files
## remoteip.csv - CSV file that includes all logical drivers of a computer with free space and total size
## remoteip.log - Log file that includes all files remove from remote folder that have more than 15 days (last write access)

# Constants

#$pathoutputfiles ALWAYS ends with \
$pathoutputfiles = "c:\path\to\output\files\"

# Read parameters

Write-Host "Enter remote computer IP (Format: ..."
$remoteip = Read-Host
Write-Host "Enter credentials for remote computer connection (Format: domain\username)..."
$credential = Get-Credential
Write-Host "Enter remote folder to scan (Format: \\server\path\) ..."
$remotefolder = Read-Host

# Get Hard Disk stats

Get-WMIObject Win32_LogicalDisk -Filter "DriveType=3" | Select-Object DeviceID,FreeSpace,Size | Export-Csv "$pathoutputfiles$remoteip.csv"

# Scan remote logs files
$stream = [System.IO.StreamWriter] "$pathoutputfiles$remoteip.log"
$files = Get-ChildItem -Path "$remotefolder" | Where-Object {$_.LastWriteTime -le [System.DateTime]::Now.AddDays(-15)}
foreach ($file in $files) {
    if ($File -ne $NULL) {
            Write-Host "Deleting File $File"
            $stream.WriteLine("Deleting File $File")
            Remove-Item $File.FullName | Out-Null
Too many email signature updates to deal with?

Do you feel like you are taking up all of your time constantly visiting users’ desks to make changes to email signatures? Wish you could manage all signatures from one central location, easily design them and deploy them quickly to users? Well, there is an easy way!

Sorry for the dalay.

I have been working, but I happily saw your reply.
It is very intesting. Now, I am working to prepare it.
With regard to the .XLS file, I would like to add the day date so I have modified in this way:

$fechadeHoy = [System.DateTime]::Now

$month = $fechadehoy.month.ToString()
$year= $fechadehoy.year.Tostring()

$stream = [System.IO.StreamWriter] "$pathoutputfiles$remoteip$day$month$year.log"


- I get "month" = 3,  I want "03"

Any advice?
