Hi @Ishtar Terra,
It's possible that the file in question is being synced incorrectly, causing it to appear as 5 TB on the OneDrive web page. One solution could be to try resyncing the file to see if that resolves the issue. Another possibility is that there is a bug or glitch in the OneDrive system causing the incorrect file size to be displayed. In this case, it may be helpful to contact Microsoft Support for further assistance in resolving the issue.
