This image I found has been uploaded for some time and has not been used on any pages. It also appears to be out of the project scope. The link is right here File:Tab error.png. Maybe we should delete the file? Thanks.

Delete Unused Image
It is actually used in a support discussion. I'm not sure why the "File usage" section shows nothing, perhaps something to do with how flow arranges content.
Okay. Then we probably should not delete it. Thank you for your quick response.
I noticed the same problem with other files. This only happens when people put the files in support discussions such as the support desk and user talk pages. That is why the file is showing up as unused.
