This message appears in the log of the elastic export. It is usually harmless and has no effect on your exports.

What the message means

After an export, the temporary file of the last export could not be deleted. A common cause: the export is saved in a folder, and another tool picks up the file there but does not delete it. The old file stays in the folder, and the next export saves under the same file name. The message then appears.

The entry is marked as an error so that it is displayed at the default logging level at all. In substance, it is more of a notice.

What you can do

1. Under Data & Plugins » Documents » Logs, check whether this is the only message that occurs. If your exports from the Elastic export are still created correctly, you can ignore the message.
2. If you want to avoid the messages, check which tool picks up the export file and have the file deleted there after it has been picked up.

The elastic export is an older technology and is no longer being developed. Catalogues are gradually replacing it.
