Lost data on icloud

Did you put it on iCloud Drive or what?

Let's do a better search though, Find Any File...

Hold Option or alt key when selecting Find to Find All.

And there's no copy on your Mac?

So this doesn't work?

On iCloud.com, you can use iCloud Drive to upload and download files, share files, delete files, organize files in folders, rename files, and recover recently deleted files. Go to icloud.com/iclouddrive and sign in using your Apple ID (the one you use with iCloud).

I don't use or trust iCloud, but have seen many instances of data magically disappearing.

Do you have a Time Machine Backup?

OK, what kind of data is missing?
