I am cleaning out files on my Mac to increase storage space, and I have two large files related to Light Room Classic My Personal Catalog. I am inclined to delete the first one (Smart Previews from 2013), but I would like advice before I make a mistake and delete something I shouldn't. The two files are:
My Personal Catalog 2-2-2-2-v10 Smart Preview.lrdata, last accessed 7/29/13, file size 22.61 GB
My Personal Catalog 2-2-2-2-v10 Previews.lrdata, last accessed 11/17/20, file size 13.5 GB

In principle you can safely delete smart previews. Lightroom can rebuild them when you decide you want them after all. The question is why you created them in the first place. Did you have a reason to create them? Did that reason change?

Thank you Johan. My reason for creating the smart previews in 2013 was that I was traveling for nearly a month and wanted to work on my photos. I still occasionally create them, but not often since I don't travel afar any more. What prompted my question was that I wondered why the 2013 previews seemed to have gotten updated to Version 10, which was the most recent update.

When you upgrade your catalogue, all the preview caches get their name changed to match the new catalogue name. Perfectly normal.
