Question:
Is the .DOWNLOAD file extension supported in Vault?
Answer:
No. When a User submits a .DOWNLOAD file to be rendered in Vault, it fails due to the file being incomplete.
A .DOWNLOAD file is a file that is currently being downloaded from the Internet or is stopped before the download finishes. If the file cannot be opened locally, it cannot be uploaded in Vault.
Note: .DOWNLOAD files are created by Apple Safari and Mozilla Firefox web browsers. If you try this method and still cannot open the file you should delete the file and download it again.
