JAKARTA - It may seem trivial, but changing the file name in large numbers manually and one by one will certainly take a lot of time, especially if the number of files is hundreds or even thousands.

That's why, many people start looking for a way to rename files at once that is easier, practical, and of course efficient. In addition to saving time, renaming files at once can also help maintain consistency in document naming.

That way, files are easier to find, share, and archive without having to open them one by one.

So, how do you rename files at once on a Windows or Mac laptop? Let's find out the answer in the following article.

Actually, both on the Windows and Mac operating systems, there are several features that can be used to change the name of many files at once.

One example of a tool that can be used is Renamer.io. This application allows you to set file naming patterns as needed, ranging from adding text, automatic numbers, to changing the letter format or file extension.

Here are the steps to use Renamer.io:

● Download and install the Renamer application from the official Renamer.io website. ● Run the application, then drag the folder or file you want to change to the main screen. ● Specify the desired rename pattern, for example: ○ Adding a prefix or suffix such as Project_ or _Final. ○ Replacing certain text in the file name. ○ Adding a sequence number automatically. ○ Changing the file extension or changing the letters to "UPPERCASE" or "lowercase". ● Note the file name changes directly through the preview feature that shows the difference between the old name and the new name. ● If the results are correct, click the "Rename" button to apply the changes to all files.
