Duplicated results using fields from relation File Usage: file I have a content type with a field image and a field file. I made a simple view to get all items of that content. I included in my view a relation ¨File Usage: File¨ to get some data like file size, upload date and uri of file field and for using VBO to download all files. 

Now Im getting duplicate results, all data (file size, upload date, vbo) for image field and the same for file field when I just want to get the information for the file field, the image is just a thumbnail. Any ideas of how to get real results over duplicates?
You need to add a File relationship for a specific field, not a File Usage relationship.

In the options for 'Add relationships' select the 'File' filter and you should see an option for each field e.g. 'File: Content using My Field'. Use this and it will give you the same data (file size etc.) but just for files attached to that field.
