Apple - Disable storage of invisible files "._" on my cfs or smb network storage

I will admit, I hadn't noticed that the defaults write command stopped working in Mavericks. However, when I DO clean network mounts, instead of your one liner find and rm, I use this:

dot_clean .

The manfile explains:

dot_clean -- Merge ._* files with corresponding native files.

I don't use the -m flag, but you may find it helpful in your situation.

-m      Always delete dot underbar files.

Here is another person actively trying to stop .DS_Store files from being created: http://www.aorensoftware.com/blog/2011/12/24/death-to-ds_store/ - looks like he doesn't want them on drives as much as he doesn't want them on the network!

Just tried, and this does work in Mavericks (at least for disabling .DS_Store not network shares):

defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool true

You just need to remember to restart Finder as well:

killall Finder

The ._ files are AppleDouble files that are used to store metadata like extended attributes, ACLs, file flags, and resource forks.

To delete them, run:

find . -name ._\* -delete

You can see if files have extended attributes, ACLs, or file flags with ls -l@eO. The ._ files are usually created because files have extended attributes. You can use xattr -c to delete extended attributes or chmod -N to delete ACLs. cp -X and rsync copy files without extended attributes, ACLs, file flags, or resource forks.
