When people have "explained" things they've talked about files and directories.
Well, for #ElderlyRelative a "file" is a place you put letters, photos, and other documents.
A "Directory" is a thing like a old-style telephone directory ... it's a document with a listing of things in it.
Then there's the confusion of putting a "File" inside a "Folder" which is inside another "Folder" which is on a drive.
No, not this drive sitting beside the computer, and not the drive inside the computer. It's actually on a drive in "The Cloud".
"How did it get there? Why don't I have it any more?"
Oh, not that cloud, the other cloud. Not "One Drive", but "Google Drive".
