If you are using a Mac, you may have noticed that macOS automatically creates .DS_Store files inside folders. These files are hidden by default because their names begin with a dot (.), so they usually go unnoticed.
However, these files often become visible when folders are shared across different operating systems, uploaded to Git repositories, or synced with cloud storage services.
.DS_Store stands for Desktop Services Store. It is a hidden system file used by macOS to store folder-specific settings such as:
The Finder automatically creates a .DS_Store file for each folder. This file travels with the folder when it is copied, archived, uploaded, or committed to a Git repository.
Generally, .DS_Store files do not harm your Mac or affect performance. However, they can expose information about your folder structure, file names, and layout preferences if accidentally shared.
This is why developers often avoid committing them to Git repositories or sharing them with production servers.
You can view hidden files, including .DS_Store, using the Terminal.
Run the following command:
ls -lAThe -A flag tells the ls command to include hidden files while excluding . and ...
To delete a .DS_Store file from a directory, use:
rm .DS_StoreTo remove .DS_Store files recursively from all subdirectories, run:
find . -name ".DS_Store" -type f -deleteTo prevent .DS_Store files from being committed to a Git repository:
.gitignore file in your project root.DS_StoreThis ensures Git ignores these files permanently.
To stop macOS from creating .DS_Store files on network-mounted drives, run the following command in Terminal:
defaults write com.apple.desktopservices DSDontWriteNetworkStores trueNote: Reboot your Mac after running this command.
To prevent .DS_Store files from being created on USB drives and other removable storage devices, run:
defaults write com.apple.desktopservices DSDontWriteUSBStores -bool trueNote: Reboot your Mac for changes to take effect.
If you want to re-enable this behavior later, use:
defaults write com.apple.desktopservices DSDontWriteUSBStores -bool false.DS_Store files in Git repositoriesManaging .DS_Store files properly helps keep repositories clean and avoids unnecessary merge conflicts.
