Files Renaming Needed After Using Ron’s Editor

Ron’s Editor is a free-to-use CSV editor for Windows. It’s neat and clean appearance and powerful functions make the long, tedious task of editing large, complex comma-separated value files (CSVs) easier.

One of the best features of Ron’s Editor is its ability to quickly load large CSV files without causing the program to freeze or crash. You can sort, manipulate the data inside your CSV files, filter the values, build a summary, or convert the file to other popular extensions (such as Excel Spreadsheet, HTML and XML).

If you’re regularly using Ron’s Editor, you might have often faced the problem of data disorganization. While the application provides handy tools and functionality, there are times when you might have run into the problem of generating illogical file names. When files are not named correctly, finding the right file can take longer than usual, or worse, you may not be able to find your file.

Unfortunately, Ron’s Editor does not provide an in-house functionality to bulk rename your CSV and other files. If you’ve got hundreds of such files, renaming them one by one is really not worth your time. In this article, we will cover different ways to rename files, including both manual and automated ones. Let’s begin.

Manually Rename Files Using File Explorer in Windows

While you can rename your files with File Explorer, there are many limitations. One of these limitations is that File Explorer does not support different file renaming rules. You can only rename your files with new names and add numbering. There is no way to change text case, replace specific characters, remove spaces, and so on. If you’re looking for those renaming options, move on to the next renaming method.

  1. Open File Explorer.
  2. Go to the folder that contains the files you want to rename.
  3. Click the downward arrow icon on the Ribbon and click the View tab.
  4. Choose Details.
  5. Now, select the files you want to rename.
    • To select all the files from the current folder, press Ctrl + A.
    • To select fewer files in a sequence, select the first file. Press and hold the Shift key and select the last file in sequence. (Shift key can be used to select files in a consecutive order while the Alt key can be used to select files randomly).
  6. Enter a new name for your files. Make sure to add a space at the end of your file name as Windows might add incremental numbers after the entered text.
  7. Press Enter.
  8. Windows will automatically rename all the selected files.

Using Command Prompt

You can also rename your files using command-lines. In contrast to File Explorer, Command Prompt supports multiple renaming methods such as adding a new text into file names, removing a few characters, replacing file extensions, and so on.

  1. Open the Start Menu, type Command Prompt in the Search Box and press Enter.
  2. Enter the following command to change the active path to the folder that contains the files:

    cd <folder path>

    cd “C:\Users\Your_User_Name\Documents”

    Important: If your folder path contains spaces, be sure to use the double quotes, otherwise the rename command may not work.
  3. Use one of the following renaming commands depending on your actual requirement:

    a) To add new text to your filenames, use the following command:


    ren *.csv ???-sales report*

b) Strip Out Characters from File Name:

If you want to script out certain character(s) from the file name, use the following command:

Example: command to strip out 5 characters and retain the remaining text:

ren *.* ?????.*

c) Replace File Extensions:


ren *.OLD *.NEW


ren *.txt *.csv

Note: Changing file extension may not always work. Merely renaming file extensions – instead of properly converting the contents of your files can cause your files to become unreadable and you may not be able to load the data. It is recommended to backup your files before changing their extensions.

Automated, Safe & Easy Method (Recommended)

Nowadays, batch renaming files has become a simple task. With the right tools, you can rename hundreds of files at a single click. The safest way to rename bulk files is to use Easy File Renamer.

  5. Once you’ve added your files, choose your desired renaming rule from the drop-down box on the left.
  6. For example, to trim certain text from the file names and make them shorter, select the Trim option and specify the length in numeric terms (for example, 3). Choose whether to trim text from the start or end.
  7. Click on Add Rule to insert the rule in the renaming queue.
  8. When you add a new rule, EFR will display the new file name previews. You can undo the added rule by clicking the Remove icon besides the applied rule.
