File states

Every file Offloft tracks has one status: the original, the scaled copy, each thumbnail and each extra format. Your site serves the cloud copy only when a file is verified. In every other normal state it serves the file on your server. You'll see these under Files and in the Media Library.

Status	What it means
pending	Waiting to be uploaded. Your site serves the local file.
uploading	Being sent to your bucket. Your site serves the local file.
uploaded	Sent, and waiting for its check. Your site serves the local file.
verified	Checked in your bucket. Your site may serve the cloud copy.
failed	The upload or check didn't succeed. Your site serves the local file.
missing_local	The file isn't on your server.
missing_cloud	The file isn't in your bucket, or doesn't match what was sent.
local_removed	Verified in your bucket, with the local copy removed by Pro. Your site serves the cloud copy.
excluded	You chose to keep this file on your server, so it is not offloaded.
deleting	Its media item was deleted in WordPress, and its cloud copy is being removed.

To see each file of a media item, open it under Files. A drawer shows each size and where it lives.
