+Powershell script for getting the number of items, folders and files in a given SharePoint Online library.
+
+ 
+
+The script requires SharePoint Online SDK.
+
+ 
+
+In order to use it, download, open and edit the file:
+
+ 
+
+```PowerShell
+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" 
+ 
+ 
+ 
+ $Username="test@tenant.onmicrosoft.com" 
+ $Url = "https://tenant.sharepoint.com/sites/test" 
+ $ListTitle = "noci" 
+ $Password = Read-Host -Prompt "Enter password" -AsSecureString
+``` 
+ 
+
+If you want to see a division between files and folders, uncomment the following part of the code:
+
+ 
+
+```PowerShell
+ 
+<# Uncomment if you want to see the split between files and folders 
+ 
+ $NoOfFiles=0 
+ $NoOfFolders=0 
+ 
+ foreach($item in $listItems) 
+ { 
+ if($item.FileSystemObjectType -eq "File") 
+ { 
+ $NoOfFiles++; 
+ } 
+ if($item.FileSystemObjectType -eq "Folder") 
+ { 
+ $NoOfFolders++; 
+ } 
+ } 
+ 
+ Write-Host "Total number of items: " $list.ItemCount 
+ Write-Host "Number of files:" $NoOfFiles 
+ Write-Host "Number of folders:" $NoOfFolders
