user channel document

[bistrita_pcv]

I uploaded a document and I see it put it in users public channel.  It has info I do not want people to see.  There is a very long key but still.  I can't figure out how to delete it.  There is no manage tab (I did a continue with google).  Can anyone tell me how to find and delete?  I find it with the key, but there is no delete
