I think the old file naming standard is still there in a way. I've wondered if when I add a prefix to the original name if that matters anymore. I just live with the repeating filenames as the dates separate the duplicates and triplicates. I just don't like it. For example this... D800_DSC1272.NEF ...is the third file with this name on my computer. I've thought of adding a couple of digits to the name with a file naming batch program but never done it.

I learned the hard way long time ago .. just change the DSC part of the file name to something that makes it hard to produce identical file names.
On my cameras where I can do renaming, as i approach that magic 9999 mark, I change the DSC to DSD, and then DSD to DSE letting the camer ado the auto incremental numbering afterwards.
But it's also important to distinguish file names form one camera to another too.
This is where I learned my lesson once when I was reorganising some files in some folders and accidentally overwritten old D70 DSC_xxxx files with newer D300 DSC_xxxx files .. and of course idiot me ignored the prompt that they were about to be overwritten!
No more. I use simple old Nikon Transfer to download images files from camera and as other software does, I add a camera model prefix(ie. D800E_DSC_xxxx) name to all files.
