Renaming multiple files on a Mac can be a daunting task, especially when dealing with a large number of files. However, with the right techniques and tools, it can be a breeze. In this article, we’ll explore the different methods to rename multiple files at once on a Mac, including using the Finder, Terminal, and third-party apps.
Rename Multiple Files Using Finder
The Finder is the default file manager on Mac, and it provides a convenient way to rename multiple files at once. Here’s how to do it:
.Navigate to the folder containing the files you want to rename.
.Select all the files you want to rename by holding the Command key and clicking on each file.
.Right-click on one of the selected files and choose “Rename [number] Items” from the context menu.
.In the “Rename Finder Items” window, enter the new name for the files in the “Name” field.
.Choose a naming format from the “Format” dropdown menu. You can choose from various formats, such as “Name and Index,” “Name and Date,” or “Custom Format.”
.If you want to add a sequential number to the file name, select the “Add number to” checkbox and choose a starting number and increment value.
.Click “Rename” to apply the changes.
This method is easy and convenient, but it has some limitations. For example, you can’t use it to rename files with complex naming patterns or to perform batch rename operations on files in different folders.
Renaming Files With A Specific Pattern
If you want to rename files with a specific pattern, such as adding a prefix or suffix to the file name, you can use the “Replace Text” feature in the “Rename Finder Items” window.
.In the “Rename Finder Items” window, click on the “Replace Text” button.
.Enter the text you want to replace in the “Find” field.
.Enter the replacement text in the “Replace with” field.
.Click “Rename” to apply the changes.
This feature is useful when you want to rename files with a specific pattern, such as adding a prefix or suffix to the file name.
Rename Multiple Files Using Terminal
The Terminal is a powerful tool on Mac that provides a command-line interface to interact with the operating system. You can use the Terminal to rename multiple files at once using various commands.
The `mv` Command
The mv command is used to move or rename files. Here’s an example of how to use it to rename multiple files at once:
.Open the Terminal app.
.Navigate to the folder containing the files you want to rename using the cd command.
.Use the following command to rename multiple files: mv oldname* newname*
.For example, if you want to rename all files with the prefix “old” to “new,” you would use the following command: mv old* new*
.The mv command is case-sensitive, so make sure to use the correct case when specifying the file names.
The `rename` Command
The rename command is a more powerful tool for renaming files on Mac. It allows you to use Perl-compatible regular expressions to rename files. Here’s an example of how to use it:
.Open the Terminal app.
.Navigate to the folder containing the files you want to rename using the cd command.
.Use the following command to rename multiple files: rename -n 's/old/new/' *
.The -n flag is used to preview the changes without actually renaming the files.
.The s/old/new/ part of the command specifies the replacement pattern. In this example, it replaces the string “old” with “new.”
.The * wildcard is used to specify all files in the current directory.
Rename Multiple Files Using Third-Party Apps
While the Finder and Terminal provide convenient ways to rename multiple files on Mac, third-party apps often offer more advanced features and flexibility. Here are a few popular options:
NameChanger
NameChanger is a popular app for renaming multiple files on Mac. It provides a user-friendly interface and supports various renaming formats, including batch renaming, sequential numbering, and custom naming patterns.
Automator
Automator is a built-in app on Mac that allows you to automate repetitive tasks, including renaming multiple files. You can create a custom workflow using Automator to rename files based on specific criteria, such as file type, date modified, or file size.

Rename is a free app that provides advanced renaming features, including support for regular expressions, custom naming patterns, and batch renaming. It also integrates with the Finder, allowing you to access its features from the context menu.
Conclusion
Renaming multiple files on Mac can be a time-consuming task, but with the right techniques and tools, it can be done efficiently. Whether you prefer using the Finder, Terminal, or third-party apps, there’s a method that suits your needs. By following the steps outlined in this article, you’ll be able to rename multiple files at once with ease.
Best Practices For Renaming Multiple Files
When renaming multiple files, it’s essential to follow best practices to avoid errors and ensure that the renaming process goes smoothly. Here are some tips to keep in mind:
Backup Your Files
Before renaming multiple files, make sure to backup your files to an external drive or cloud storage service. This ensures that you can recover your files in case something goes wrong during the renaming process.
Use A Consistent Naming Convention
Use a consistent naming convention for your files to avoid confusion and ensure that your files are easily identifiable. This is especially important when working with large collections of files.
Test Your Renaming Script
If you’re using a renaming script or third-party app, test it on a small batch of files before applying it to a large collection of files. This ensures that the script or app works as expected and avoids any errors.
Document Your Renaming Process
Document your renaming process, including the steps you took and the tools you used. This ensures that you can repeat the process in the future and provides a reference for others who may need to rename files.
By following these best practices, you’ll be able to rename multiple files on Mac efficiently and effectively.
What Is Batch Renaming, And Why Is It Useful?
Batch renaming is a process of renaming multiple files at once using a set of rules or patterns. This feature is useful when you need to organize a large number of files, such as renaming a batch of photos or videos, or when you want to add a prefix or suffix to multiple files. Batch renaming can save you a significant amount of time and effort compared to renaming files individually.
With batch renaming, you can perform various operations, such as replacing text, adding numbers, changing case, and more. You can also use regular expressions to match patterns and perform complex renaming tasks. Additionally, many batch renaming tools offer preview features, which allow you to review the changes before applying them to your files.
What Are The Different Ways To Batch Rename Files On A Mac?
There are several ways to batch rename files on a Mac, including using the Finder’s built-in rename feature, third-party applications, and command-line tools. The Finder’s built-in rename feature allows you to rename multiple files at once, but it has limited functionality. Third-party applications, such as NameChanger and Hazel, offer more advanced features and flexibility. Command-line tools, such as Finder’s rename utility and zsh shell, provide a high degree of customization and scripting capabilities.
Each method has its own strengths and weaknesses, and the choice ultimately depends on your specific needs and preferences. If you need a simple and easy-to-use solution, the Finder’s built-in rename feature or a third-party application might be the best choice. If you require more advanced features and customization options, a command-line tool might be the way to go.
How Do I Batch Rename Files Using The Finder On Mac?
To batch rename files using the Finder on Mac, select the files you want to rename, right-click (or control-click) on one of the selected files, and choose “Rename [X] Items” from the context menu. In the “Rename” window, select the “Replace Text” option and enter the text you want to replace and the replacement text. You can also choose other options, such as “Add Text” or “Format”, depending on your needs.
Once you’ve entered the rename criteria, click the “Rename” button to apply the changes to the selected files. The Finder will display a preview of the renamed files before applying the changes, allowing you to review and cancel if needed.

How Do I Use Regular Expressions In Batch Renaming?
Regular expressions (regex) are a powerful pattern-matching language that can be used in batch renaming to perform complex operations. To use regex in batch renaming, you’ll need to enable the regex option in your chosen batch renaming tool. Once enabled, you can enter a regex pattern in the “Find” field, and the replacement text in the “Replace” field.
Regex patterns allow you to match specific patterns in file names, such as dates, numbers, or text strings. You can use regex to extract specific parts of a file name, or to perform complex operations, such as removing or replacing characters. With regex, you can create custom renaming rules that match your specific needs.
Can I Undo Batch Renaming Operations On Mac?
The ability to undo batch renaming operations on Mac depends on the tool or method you’re using. The Finder’s built-in rename feature does not offer an undo option, so it’s essential to review the changes carefully before applying them. Third-party applications, such as NameChanger and Hazel, often offer an undo feature, allowing you to revert to the original file names if needed.
If you’re using a command-line tool, you may not be able to undo the changes, so it’s crucial to review the changes carefully before applying them. To be safe, it’s always a good idea to create a backup of your files before performing a batch rename operation.
Are There Any Batch Renaming Best Practices I Should Follow?
Yes, there are several batch renaming best practices you should follow to ensure that your renaming operations are successful and efficient. First, always create a backup of your files before performing a batch rename operation. Second, carefully review the changes before applying them, and use the preview feature if available.
