Managing files and folders on your Mac can be a daunting task, especially when you need to compare two folders to identify differences or duplicates. Whether you’re a professional photographer, a developer, or a student, you’ve likely found yourself in a situation where you need to compare two folders on your Mac. But, how do you do it? In this article, we’ll delve into the world of folder comparison on Mac and explore the various methods to help you achieve your goal.
The Importance of Folder Comparison
Before we dive into the nitty-gritty of comparing folders, let’s take a step back and understand why folder comparison is essential in today’s digital age. With the exponential growth of digital data, it’s easy to accumulate duplicate files, outdated versions, and unnecessary files that take up valuable storage space on your Mac. Folder comparison helps you:
- Identify duplicate files and eliminate them to free up storage space
- Detect changes between different versions of files
- Merge changes from one folder to another
- Verify the integrity of backed-up data
- Simplify file organization and management
Using the Finder to Compare Folders
One of the most straightforward ways to compare two folders on your Mac is by using the built-in Finder app. Here’s how:
Method 1: Visual Inspection
- Open the Finder app and navigate to the two folders you want to compare.
- Select both folders by holding the Command key while clicking on each folder.
- Right-click (or Control-click) on one of the selected folders and choose “Get Info” from the context menu.
- In the Get Info window, you’ll see a list of files and folders within each selected folder.
- Manually scan the list to identify differences or duplicates.
This method is time-consuming and prone to human error, especially when dealing with large folders. However, it’s a simple way to get a quick overview of the contents of each folder.
Method 2: Using the “List” View
- Open the Finder app and navigate to the two folders you want to compare.
- Select one of the folders and click on the “List” view button in the toolbar.
- Sort the files and folders by name, date, or size to make it easier to compare.
- Repeat the process for the second folder and compare the sorted lists.
This method is more effective than visual inspection, but it still requires manual effort and attention to detail.
Using Third-Party Apps to Compare Folders
While the Finder app provides basic functionality, third-party apps offer more advanced features and automation to simplify the folder comparison process.
DiffMerge
DiffMerge is a popular, free app that allows you to compare and merge files and folders. Here’s how to use it:

Using the Terminal to Compare Folders
For advanced users and developers, the Terminal app provides a command-line interface to compare folders using various commands.
Using the “diff” Command
The “diff” command is a powerful tool for comparing files and folders. Here’s an example:
- Open the Terminal app and navigate to the directory containing the two folders you want to compare.
- Use the following command:
diff -r folder1 folder2
- The “diff” command will generate a report highlighting the differences between the two folders.
Using the “find” Command
The “find” command can be used to compare folders based on specific criteria, such as file size or modification date. Here’s an example:
- Open the Terminal app and navigate to the directory containing the two folders you want to compare.
- Use the following command:
find folder1 folder2 -type f -size +10k
- The “find” command will generate a list of files larger than 10KB in both folders.
Conclusion

What is the purpose of comparing two folders in Mac?
The purpose of comparing two folders in Mac is to identify the differences between them. This can be useful in various scenarios, such as when you need to sync two folders, identify duplicate files, or track changes made to files over time. By comparing folders, you can quickly and easily see which files are missing, have changed, or are identical in both folders.
This can be especially useful for developers, designers, and other professionals who work with multiple versions of files and need to keep track of changes. Additionally, comparing folders can also be useful for personal users who want to ensure that their files are backed up correctly or who need to merge files from different sources.
What are the different methods to compare two folders in Mac?
There are several methods to compare two folders in Mac, including using the built-in diff
command in the Terminal, using third-party applications such as Beyond Compare or FileMerge, and using cloud-based services such as Google Drive or Dropbox. Each method has its own strengths and weaknesses, and the choice of method depends on the specific needs and preferences of the user.
The diff
command is a command-line tool that allows users to compare the contents of two folders and identify the differences. Third-party applications such as Beyond Compare and FileMerge provide a more visual and user-friendly interface for comparing folders. Cloud-based services such as Google Drive and Dropbox allow users to compare folders online and collaborate with others in real-time.
How do I use the `diff` command to compare two folders in Mac?
To use the diff
command to compare two folders in Mac, open the Terminal application and navigate to the folder that contains the two folders you want to compare. Then, type the command diff -r folder1 folder2
and press Enter. The -r
option stands for “recursive” and tells the diff
command to compare the contents of the two folders recursively.
The diff
command will then display a list of files that are different between the two folders, including files that are only present in one folder or files that have different contents. You can customize the output of the diff
command by using various options, such as -q
to suppress the display of identical files or -s
to display a summary of the differences.
What are the advantages of using third-party applications to compare two folders in Mac?

These features can be especially useful for users who need to compare large folders or complex folder structures.
How do I merge changes between two folders using third-party applications?
To merge changes between two folders using third-party applications, you typically need to select the files or folders that you want to merge and then click on the “Merge” button. The application will then copy the selected files or folders from one folder to the other, overwriting any existing files with the same name.
You can customize the merge process by selecting which files to merge, how to handle conflicts, and what to do with deleted or added files. For example, you can choose to merge only files that have changed, or to merge all files regardless of whether they have changed or not. You can also choose to move deleted files to a separate folder or to delete them permanently.
