Errors while copy from dropbox to local

hello using copy from dropbox to local FS i got multiple error as:

any idea? how can i be 100% sure that all files without any corruption was mirrored from my dropbox account to local FS? Does Dropbox provides some details about files stored there (ie total size, number of files etc…)

thank you

rclone -P copy dropbox: .

inside that dir is also other file jquery-ui-1.8.custom.min.js which was copied to local storage

Manual download of files query-1.4.2.min.js via dropbox web ui works fine.

Is your backup encrypted? You can use rclone cryptcheck or if not encrypted, you can use rclone check.

no i downloaded everything from dropbox to my local drive and i wanted to check if eveything was really downloaded it number and total size on dropbox to local drive… but as was reported i got these 4 errors ie these 4 files were not downloaded… but maybe something else? who /how to know?

looks likes dropbox web ui provides only Using 22.81 GB of 1.02 TB nothing else.

That error means that the file in question has been copyright blocked I think.
