No warning of duplicating name for SW files

Hello,

if I create a non solidworks file (word document, image, etc.) with the name that already exists in the vault, then I instantly receive a warning in taskbar that I have to pay attention to it. However, if I create a solidworks file (e.g. a part) with a duplicate name, I receive no warning, and am only informed about duplication when checking in the file, facing an error "File name is not unique".  Why is that? How do I make EPDM give me a warning for SW files as well? EPDM 2015 SP4

Thank you for your advice
