To make the first batch file for lock folder, grab the following code from here and paste it in notepad file and then, save (Ctrl+S) it named- lock.bat. You can save it by any name (based on you) but, extension should be .bat due to it is batch file. The Following code is- 

ren foldername foldername.{21EC2020-3AEA-1069-A2DD-08002B30309D}

ren locked locked.{21EC2020-3AEA-1069-A2DD-08002B30309D}
