The above link you can use multiple batch programs that will optimize all of your photos in one shot. Just backup your photos first before you do anything.

Or you can use Visual Studio https://www.visualstudio.com/
using a extension from https://marketplace.visualstudio.com/items?itemName=MadsKristensen.WebExtensionPack2017

Web Essentials 2017 Mads Kristensen

Either way will BATCH shrink all of your photos in your entire server or directory in various formats.

Both work equally well.
