The .DS_Store file is a hidden file that is created by the Finder on Mac OS X. It stores information about the files and folders in a directory, such as their position, size, and modification date. This file is used by the Finder to display the contents of a directory and to keep track of changes to the directory.
When you access a network volume from a Mac, the Finder will create a .DS_Store file on the volume. This can be a problem if you are using a network volume that is shared with other users, as the .DS_Store file can contain sensitive information about the files and folders on the volume.
To prevent the Finder from creating .DS_Store files on network volumes, you can use the following steps:
Open the Terminal application.
Type the following command:
defaults write com.apple.desktopservices DSDontWriteNetworkStores true
Press Enter.
This will prevent the Finder from creating .DS_Store files on network volumes.
If you want to re-enable the creation of .DS_Store files on network volumes, you can use the following steps:
Open the Terminal application.
Type the following command:
defaults write com.apple.desktopservices DSDontWriteNetworkStores false
Press Enter.
This will re-enable the creation of .DS_Store files on network volumes.
