Powershell – Why can’t I get the size of network shared folder? by powershell

network-sharepowershell

I've already know a sharespace path: \sharespace\test1

I used this line to get the latest update folder under this path:

$lastbuild=get-childitem $var.droppath.TrimEnd()|where-object {$_.name -match "10."} |Sort-Object -Property LastWriteTime -Descending | Select-Object -First 1
$lastbuild.fullname.TrimEnd()

what I got is \\sharespace\test1\10.0.1212.1

How can I get this folder's size? I used the following code, but only get the totalsize of its parent path\\sharespace\test1

$mapbuild.mapNetworkDrive("u:",$lastbuild.fullname.TrimEnd())

$fsobuild = new-Object -com Scripting.FileSystemObject

$dobuild = $fsobuild.getdrive("u:")

Write-host "Size of latestbuild:"

$dobuild.totalsize

This looks like exactly what you need: Scripting Guy article on getting folder size

I think it's important to note that powershell can typically handle UNC paths natively, so there's no need to map a drive. You should be able to do something like this:

$fsobuild = new-Object -com Scripting.FileSystemObject
"{0:N2}" -f (($fsobuild.GetFolder($lastbuild.Fullname).Size) / 1MB) + " MB"

Powershell – Determine Users Accessing a Shared Folder Using PowerShell

I came up with the following script:

$computer = "LocalHost"
$namespace = "root\CIMV2"
$userSessions = Get-WmiObject -class Win32_ServerConnection -computername $computer -namespace $namespace

if($userSessions -ne $null)
{
    Write-Host "The following users are connected to your PC: "

    foreach ($userSession in $userSessions)
    {
        $userDetails = [string]::Format("User {0} from machine {1} on share: {2}", $userSession.UserName, $userSession.ComputerName, $userSession.ShareName)
        Write-Host $userDetails
    }    

    Read-Host
}

As always, if you can't find a way to do it in PowerShell, see if someone has done something similar in C#.

Windows – How To Disconnect Users Accessing a Windows Shared Folder using PowerShell

Until I find a WMI (e.g. based on something like Win32_ServerConnection) or .NET object solution that lets me deal with the list of connections as first class objects rather than parsing the text output, I've come up with this solution based around the OpenFiles utility. I'm fairly concerned that it's fragile and not that obvious to modify for different needs but it seems to be working for my narrow scenario at the moment. I've kept the regex with named captures for the other parts of the output as a reference for if you need to use different parameters for openfiles /disconnect (/A /ID /OP).

Note that repeated use of Select-String is something I don't fully understand but is to do with the fact that this is necessary to get access to the named captures. See this RegEx Named Groups with Select-String posting for details. Happy to change it if someone can tell me how!

$computerName = 'ServerName'
$pattern = '^.+ (?<FileId>\d+) (?<User>[^ ]+).+ (?<OpenFile>C:.+\\SpecificFolder\\.*)$'
$openfiles = openfiles /query /s $computerName /v | Select-String -Pattern $pattern | ForEach-Object {[void]($_.Line -match $pattern); $matches['OpenFile']}
$openfiles | Sort-Object -Unique | ForEach-Object { openfiles /disconnect /s $computerName /a * /op `"$_`"}
