• Dealing with those annoying .DS_Store files

To configure a Mac OS X user account so that .DS_Store files are not created when interacting with a remote file server using Finder (note that this will affect the user's interactions with SMB/CIFS, AFP, NFS, and WebDAV servers):

1. Open Terminal

2. Execute:

    defaults write com.apple.desktopservices DSDontWriteNetworkStores true
   

3. Either restart the computer or log out and back in to the user account

4. 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 the newly modified com.apple.desktopservices.plist file to the ~/Library/Preferences folder of other user accounts
