Mistake in uploaded file type after revision I have revised my manuscript in Elsevier's journal and uploaded it along with the point-by-point reviewer comments responding. I found I have made a mistake in uploading the file.

There is the list of file types need to submit in the author page as follows:
1. Manuscript (revised manuscript)
2. Respond to reviewer
3. Revised manuscript with Changes marker

For the file type number 3, I uploaded the wrong file, which lists the changed in manuscript in detail instead of the full manuscript with changes marked.

I wonder Do I need to write an email to the editor to explain about that? Anyone has experience in this problem please give me the advice.

One more question: how long should we wait for the status change from "with journal" to "with editor" or "under review" for the revised manuscript?
Mistakes can happen.
You should email the editor or they might notice it and ask you to upload the correct one.

It depends on the journal, you should check the journal website for more information or ask directly the editor.
