Make sure your uploaded files should serve a purpose. If no page uses them in any way, the file will be deleted.
Use the Upload form to upload single files, or Multiple Upload form for multiple files at once (up to twenty at one time).
Duplicate videos should not be uploaded unless intended to replace a lower quality version of the same image. In this case, go to the video page and click on "Upload a new version of this file" Remember, Wikia is not a free personal hosting site, web storage facility, or video repository.
