It is possible to upload files with the name, just as long as the file extensions are different. If the file extensions are the same the original file will be replaced in the Asset Gallery. If the file extensions are not the same Brandifyer will make an ‘Asset Variant’. Images and videos will be shown once in the Asset Gallery, however all variants of that image or video will be visible in the right hand menu. Select a variant to download or to see the details.
This article also has a Youtube video to show how this action can be done.
