What is cvws.iCloud content?

To effectively help you in this setting where we can neither see nor touch your Apple device, we need more context from you:

• What Apple device?
• What operating system is it running?
• Where did you see this filename? Running an app? In an error message? in a diagnostic report?

Right now you have us guessing, and that seldom has a good outcome!

I'm using a MBk Pro, 16" 2019 with Monterey 12.5. The info beneath the Safari tab for this open file shows it as "cvws.icloud-content. What does this mean? Is there an explanatory article?
