What is a DS_STORE file?
A .DS_STORE file is a hidden configuration file created by the macOS Finder. Developed by Apple, it stores custom attributes of its containing folder. This includes icon positions, window sizes, and background images. It is also recognized as a Mac OS X Folder Settings File.
Why do I see DS_STORE files?
The macOS Finder automatically hides .DS_STORE files from standard users. You usually see them when you transfer a folder from a Mac to a Windows or Linux computer. They also appear in compressed .ZIP files or inside version control systems like Git.
How to open DS_STORE files?
Most users do not need to open .DS_STORE files manually. However, developers and system administrators sometimes inspect them to view folder metadata. You can read the raw data using command-line tools or a Hex Editor. For a simple and immediate solution, viewer.online/ds_store analyzes .DS_STORE files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Best practices and troubleshooting
You can safely delete a .DS_STORE file. If you delete it, macOS Finder simply loses the custom folder settings and generates a new .DS_STORE file automatically the next time you open the directory. Web and software developers should configure their version control systems to ignore these files to prevent uploading hidden macOS settings.
Summary
Because .DS_STORE files use the known ds_store format, viewer.online/ds_store can safely open and display them online, eliminating compatibility problems. If your specific file has multiple possible meanings, we recommend using viewer.online/ds_store to identify the actual format of the user's file.
