To configure a Mac OS X user account so that .DS_Store files are not created when interacting with a remote file server using the Finder, follow the steps below.
Note: This will affect the user’s interactions with SMB/CIFS, AFP, NFS, and WebDAV servers.
1. Open the Terminal.
defaults write com.apple.desktopservices DSDontWriteNetworkStores true
3. Press Return.
4. Restart the computer.
If you want to prevent .DS_Store file creation for other users on the same computer, log in to each user account and perform the steps above—or distribute a copy of your newly modified com.apple.desktopservices.plist file to the ~/Library/Preferences folder of other target users.
