I have installed all of the updates for Lightroom 5 and now have a bunch of folders on my computer. Can I delete the folders with the older versions of LR5 and just keep the most recent folder (LR5.7)?
Moving this discussion to the Photoshop Lightroom forum.
Yes. Each version of Lightroom is a complete program that does not rely on previous versions of the program for anything. If you are using a Windows PC installing an update will remove all the program files from the previous version. On the Mac you have to delete the program as well.
