If you use your Mac on a cross platform network often, you’ve surely run into the obnoxious creation of .DS_Store files. If you’re curious what the file is used for, DS_Store is a hidden file for Mac OS X that stores various bits of data for the Finder to remember, like icon position, making it completely useless for anyone besides you to see. By default, your Mac will create the .DS_Store file’s all over the place including accessed computers that aren’t Macs, creating an annoying mess for network users to find. Thankfully you can easily turn off the creation of DS_Store files on network connections:
Stop .DS_Store file creation on network shares
Launch the Terminal and type the following exactly:
defaults write com.apple.desktopservices DSDontWriteNetworkStores true
Restart your Mac and you will no longer have those pesky .DS_Store files appearing every time you browse a network share.
do you know how to extend this feature to external drives, SD cards, USB keys etc ?
