Photoshop versions necessary?

Lightroom Version Number

12.1

Operating System

1. macOS 13 Ventura

I'm having computer slow downs so I'm trying to clean get rid of some old and unused programs. There are three versions of Photoshop on my hard drive, 2021, 22 and 23. Is there any reason to keep the two older versions?

No, none except if you have some old plugins that still work in an older version but not in PS 2023.

Thank you, didn't see a reason to keep them but thought I'd check as I'm not a computer wiz.

PS2021 has Filter>Sharpen>Shake reduction.
Adobe dropped it with 2022.
Its worth the disk space for me. Its a terrible interface but it can sometimes rescue shots where you've used too slow a shutter speed. For me that's trying to hand hold inside a cathedral, or when stitching a hand held panorama and one shot in the middle is a bit blurry.
