I noticed this folder, ~/Library/Application Support/calls-and-messages, taking up almost 24GB (mostly in the Backup subfolder). It seems like it's being used almost every day, and it contains log files that seem to indicate that it's created by the OS, but I can't tell exactly what it's for and if it deserves that much disk space.
Is it safe to just delete since it's so huge? Can I change the max size of the backup somewhere?
I believe I was on the latest version of macOS 13 when I first found this. I have since updated to Sonoma.
The only messaging related app I use, outside of Messages, is Zoom, although I haven't used it in a few days and the files in this folder are still getting updated.

as executed in the Terminal. Without actual filename details, it's going to be difficult to work out what application may be causing this. It doesn't sound like any standard OS component. Also please add what macOS version you are using and what messaging apps you might use.
