How to Fix File Preview Errors

A successful upload does not guarantee an in-browser preview. Some formats may require downloading and compatible software.

Check the File

Confirm that upload processing completed and that the file can be opened locally.

Check Format Support

TERA advertises previews for many common documents and media formats, but preview capabilities vary by specific format and file condition.

Try Standard Fixes

Refresh the page, check your connection and use a current browser. Avoid deleting the original file solely because preview failed.

Use a Local Viewer

When the preview is unsupported, download the file if your permissions permit and open it in an appropriate application.

Ask for Help

Report the file extension, approximate size and error text. Do not disclose confidential document contents unless necessary and authorized.
