Many years ago when I had even less knowledge about computer science than I have now, I developed the habit of periodically copy-pasting save files from the directory to a "backup" folder at the same level. I seem to recall I first developed this habit with Oblivion, but then carried it over to other studio's products and do it for all Bethesda games (and others too). For example, move files
From:
C:\Users\Anthropoid\Documents\My Games\Fallout4\Saves
To
C:\Users\Anthropoid\Documents\My Games\Fallout4\Elsa Randolph
When I developed this habit, I was convinced it helped game performance and helped reduce CTDs or other issues. Now that I have a year or so of IT coursework under my belt and I am prepping to take the MCSE certification exam, I have to say, it doesn't make any sense to me that the number of files in the directory would have _any_ impact on game performance.
Can someone with greater expertise than me clarify if this is just voodoo I'm engaging in or if there is an empirical reason it might impact game performance?
