dot_clean
In other words, to clean out the "dot" files in my Dropbox, I hit dot_clean ~/Dropbox/. I even set up a "Cron" tab with Cronnix to clean them out every day, but of course it does absolutely nothing for some reason. I have to enter the command manually in Terminal every time I want to clean out my Dropbox.
Sometimes it just feels good to find a solution to a problem, but then again, maybe this problem shouldn't exist to begin with. That's when you type the following command into Terminal and restart:
defaults write com.apple.desktopservices DSDontWriteNetworkStores true
I'm still not entirely sure what purpose these "dot" files serve.
