How to Rename Files in Bulk in Windows

📅 Published: May 3, 2026

Renaming files can be easy if the number of files is countable, like 5 or 10, but renaming becomes a headache when the total number of files is significantly high, in numbers like 50 or 100. If you have fewer files, then you can easily rename your files one by one using our renamefile.online tool, but if it has large numbers, then this article is for you. In this article, I will be sharing the ways through which you can rename a large quantity of files within a few steps.

Before knowing how to rename files in bulk, first let us understand why renaming files is important.

Why is renaming files important?

One may think that renaming is easy and not an important thing, but I must tell you that renaming files is one of the important aspects of managing files. Apart from an organisation or company, renaming files is even more important for a single person. I explain this through an example. Suppose a image file have a name hd_ede48.jpg and a image file have a name lastsunset_2025.jpg, which one according to you give more clarification about the image, the second one right.

Giving a proper name to any files gives you the ability to easily search for the exact file from the search box. Some even save their files using a proper format, like putting the name, date, as well as other details in the file name, so that anyone can know what the file is all about just by reading the file name. Also, if you know the format, then you can find the exact file within seconds using the search box.

Using a proper file name gives instant context about the file, like instead of using document.pdf, if we use result_quarter2_2025.pdf, then it gives more clarity about the file that the file is related to the quarter 2 results of 2025.

Also, using the generic name can sometimes create an overwriting problem, like downloading a resume with a resume.docx file name, then the system will ask you to replace the file in the storage if you already have the same file name in the file storage. It is a big problem with generic names when you download files. Renaming a good solution for it.

Sorting files can be easy if you use a specific prefix in the file name, like 12-08-2025_report.pdf. Through this, you can force your files to stay in a logical order regardless if you edit the file anytime.

Here are the methods through which you can bulk rename your files in Windows OS

I suggest two simple methods through which you can bulk rename files. However, there are other methods also, which are more complex in nature.

1. Using File Explorer

This method is simple in which you don't have to go anywhere or install anything, you just need a Windows system. This method is famous for sequential numbering, in which a group of files is given the same name followed by a number like rename1, rename2.

Step 1: Open your folder and select all the files that you want to rename. I hope you know how to select all the files.

Step 2: While all files are selected, right-click on any one of the selected files and select the " rename" option from the shown menu. Alternatively, you can also press the F2 key on your keyboard.

Step 3: Enter the base name you want for all the files (like file number) and press Enter.

Step 4: All the files will automatically be renamed to your base name with sequential numbers.

2. Microsoft Powertoys PowerRename

This method is a little complex; here you have to install Microsoft PowerToys. This method is used for replacing specific words or adding timestamps.

Step 1: If you don't have Powertoys then Install it into your system.

Step 2: Once completely install then go to File Explorer and select all the files that you want to rename. Right-click and choose Rename with PowerRename.

Step 3: Enter the text you want remove and replace with new text.

Step 4: Click on the Renamed column for a live preview. If it look ok for you then click apply and you are done.

These are one of the simplest methods through which you can easily rename a large quantity of files within few seconds.

Third Parties tools for Bulk Renaming

There are some tool available on the Internet that you can used for bulk renaming of files. These tool are generally free and offer various methods, changes, and adding timestamps. You can search on the Google search and easily find bulk renaming tools.

Descriptive Naming is Best

Descriptive naming is best because it look professional and very easy to understand about what the file contain inside without ever double-clicking it, saving seconds that add up to hours over a year. Starting with YYYY-MM-DD (for example, 2024-05-03_ProjectAlpha) ensures that your files remain in chronological order, regardless of when they were last edited. It is also easy to remember, Descriptive names act as a message to your future self.
