No technical reason. I’m just darn user friendly, and I know underscores or dashes (looks at Dan Poynor) are not something users like to see on filenames. Client devices are fine with spaced filenames. I also think not slapping filenames with underscores looks professional since no cloud storage system does it at least when downloaded.
I was hoping there’s a hook I could call and use str_replace

I tried it placing it there and every other possible position, but nothing worked. I found a plug-in that solved my problem.
