Disable .DS_STORE file creation on network shares
On an OSX system, .DS_STORE (Desktop Services Store), are used to store user settings for a folder, such as the list of files, the location of the icons, the selected background image.
In a mixed-OS environment using network shares, they can be annoying.
Even in a strictly Apple environment, there are security implications, as they do store data.
Besides just cluttering up your directories, the .DS_STORE file can contain potentially sensitive information.
To disable the creation of .DS_STORE files in network shared, from a terminal prompt:
defaults write com.apple.desktopservices DSDontWriteNetworkStores true
Then reboot.
