此页面可让您了解特定网站的每个子网站的大小。

使用 PowerShell 获取 SharePoint Online 中的子网站大小

作为 SharePoint Online 管理员，您可以使用 PowerShell 获取网站集或子网站的大小。当尝试确定哪些网站集或子网站使用最多的存储空间时，这非常有用。以下是用于获取 SharePoint Online 中子网站大小的 PowerShell：

#Load SharePoint CSOM Assemblies
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"
 
#Function to Get the size of a Folder in SharePoint Online
Function Get-SPOFolderSize([Microsoft.SharePoint.Client.Folder]$Folder)
{ 
     Try
     {
        Write-host -f Yellow "Size of the Folder '$($Folder.ServerRelativeUrl)' : " -NoNewline
        
        $FolderSize = 0
        #Get all Files and Subfolders from the folder
        $Ctx.Load($Folder.Files)
        $Ctx.Load($Folder.Folders)
        $Ctx.ExecuteQuery()

        ForEach($File in $Folder.Files)
        {
            #Get File Size
            $FolderSize += $File.Length
        }
        Write-host $FolderSize

        #Process all Sub Folders
        ForEach($Folder in $Folder.Folders)
        {
            #Call the function recursively
            $FolderSize +=Get-SPOFolderSize $Folder
        }
        Return $FolderSize
    }
    Catch [System.Exception]
    {
        Write-Host -f Red "Error:"$_.Exception.Message
    }
}
 
#parameters
$SiteURL = "https://Crescent.sharepoint.com/unitedstates"
 
#Get credentials to connect to SharePoint Online Admin Center
$Cred = Get-Credential
 
#Set up the context
$Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
$Ctx.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.Username, $Cred.Password)
   
#Get the Web
$Web = $Ctx.Web
$RootFolder = $Web.RootFolder
$Ctx.Load($RootFolder)
$Ctx.ExecuteQuery()

#Call the function to get Subsite size
$SubSiteSize = Get-SPOFolderSize -Folder $RootFolder

#sharepoint online powershell site size
Write-host "Toal Size of the subsite (MB): " -NoNewline
[Math]::Round($SubSiteSize/1MB, 2)

此 PowerShell 脚本获取给定子网站的大小。如何检索网站集中所有子网站的存储消耗情况？
