+The script retrieves all files and restores the LAST NOT CURRENT version of the file.
+
+Please test the script in test environment before using it in production.
+
+ 
+
+The script is a modification of the existing Restore Previous Versions script created to show 2 ways on filtering the file results. The filters are only examples that need to be adjusted to your specific needs.
+
+The first filter uses CamlQuery to retrieve only files coming from a specific folder.
+
+The second filter takes files we have already retrieved and selects only those modified after 12/2/2017.
+
+When dealing with large number of files CamlQuery is the preferred and more efficient way.
+
+ 
+
+ 
+
+ The script requires SharePoint Online SDK.  Make sure that the paths below point to locations on your computer:
+
+ 
+
+PowerShell
+#Paths to SDK 
+Add-Type -Path "c:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.dll"   
+Add-Type -Path "c:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"   
+ 
+ 
+
+ 
+
+ 
+
+The script needs to be edited before running. Enter the necessary data:
+
+ 
+
+```PowerShell
+#Enter the data 
+$AdminPassword=Read-Host -Prompt "Enter password" -AsSecureString 
+$username="t@testova365.onmicrosoft.com" 
+$Url="https://testova365.sharepoint.com/sites/STS" 
+$ListTitle="VersionTest"
+``` 
+The CamlQuery below chooses only files whose ServerRelativeUrl includes a certain path. In this way you can restore versions only from a specific folder.
+PowerShell
+ $spqQuery.ViewXml ="<View Scope='RecursiveAll' /><Where><Eq><FieldRef Name='ServerRelativeUrl'/><Value Type='Text'>/VersionTest/Folder2/FolderWithinFolder</Value></Eq></Where>"; 
+ 
+ The following lines allow us to narrow the files only to those modified after 12/2/2017. 
+PowerShell
+        $date=Get-Date ("2/12/2017") 
+         
+        if($file.TimeLastModified -gt $date)
