Hello,

This is not the most beautiful script I wrote, but functional it is J

The script is tested on SQL 2014. So I’m not sure if it will work on other SQL versions…

#check if the path is typed correctly, without a \ at the end

if ($NewLogLoc.EndsWith('\') -eq $true){$NewLogLoc = $NewLogLoc.Substring(0,$NewLogLoc.Length-1)}

#In some cases a DBA wants to locate the log file on an other disk. So that is why you have to add the path here as well
