I’m beginning to get annoyed about all of the hidden/system files and directories that have begun to litter through my NFS server. In particular, there are two.
The first is the .DS_Store files. These come from OS X Finder and are written every time a directory is accessed. I find them all over my NFS directories on my NAS. Apple has a KB note about how to turn these off over network connections. You can actually go one step further and disable the file creation globally.
defaults write /Library/Preferences/com.apple.desktopservices DSDontWriteNetworkStores true
This will write the plist for the system wide preferences.
I’ve also seen a post that this should also work on USB or local drives with the key
DSDontWriteLocalStores. I haven’t tried any of this though — just a warning.
The other directories that litter my NAS are the @eaDir directories. These are created on my Synology DS212 NAS. There is a post that details how to prevent the creation of these directories. Basically, these are created by a bunch of indexing daemons.
To find all of the files on the command line you can use:
find . -name .DS_Store -type f to search down from the current directory and optionally remove it with the pipe
| xargs rm -rf
find . -name @eadir -type d
