This media was proposed for deletion as a replaceable non-free content. It was reviewed by an administrative user, or another user, who declined the deletion, judging that no adequate free-licensed file exists or can be created to fulfill the limited role performed by this file at the time deletion was considered. However, this file may be replaceable by a free file in other contexts, and in such cases the free file must take precedence. A discussion of this decision may exist on the file talk page.

This template is for proposed files only. For non-proposed files, use {{Do not replace-F7}} instead.
