In daily file management, we often encounter the situation of modifying folder names. Besides possibly adding files at the beginning or end, it is more common to insert specific information right in the middle of the name. For example, inserting a year date in the middle of [Project A Contract] to become [Project A 2025 Contract]. This requirement is especially common when organizing documents, materials, and categorizing photo files. Inserting text in the middle of a folder name is indeed a very troublesome thing. If you rename folders one by one, select the middle part and then input the text, a few folders can be quickly and effortlessly resolved. However, if there are hundreds of folders that all need to be uniformly added, the entire process is not only tedious and boring but may also result in errors.
Actually, we can achieve precise insertion in the middle of folder names using simple command-line instructions or small tools. Here, we introduce three practical solutions to help us manage files more efficiently.
When Do You Need to Batch Add Text to Rename Within the Middle of Multiple Folders?
Inconsistent Folder Naming
After long-term accumulation, you'll find that many folders at the same level have various naming rules. Some lack project names, others have no dates or identifiers, making them unintuitive. When these folders are distributed across multiple directories and you need to uniformly insert a piece of text in the middle of their names, we can batch add it directly in the middle of the folder names to avoid manual modifications.
Need to Differentiate Content
Folders have different uses at different stages but are not always marked in detail initially. When differentiation is required later, a uniform identifier must be added in the middle of the folder names. If the number of folders is large, the hierarchy is deep, and they are scattered across multiple parent folders, manual modification is prone to omissions and errors. Renaming folders in batches can quickly resolve these issues.
Improve Work Efficiency
When the number of folders reaches dozens or hundreds, renaming each folder is not only time-consuming but also leads to naming inconsistencies. Issues like different insertion positions or spelling errors will cause more confusion. Batch adding text within the middle range of folder names can complete the process in one go, making the entire directory structure clearer, which facilitates searching, backup, and subsequent organization.
Preview of the Effect of Batch Adding Text and Numbers in the Middle of Folder Names
Before processing:

After processing:

Method 1: Use HeSoft Doc Batch Tool to Batch Precisely Insert Text in the Middle of Folders
Recommendation Index: ★★★★★
Advantages:
- Can be precise to the character level, allowing insertion after the Nth character, and supports negative numbers to calculate position from the end.
- Hundreds or thousands of folders can be batch processed. All files are processed locally with no upload requirements, protecting file privacy and security.
Disadvantages:
- Requires installing the software on a computer.
Operation Steps:
1. Open [ HeSoft Doc Batch Tool ], select [Folder Name] - [Insert Text into Folder Name].

2. Click [Add Folders], then add the folders you need to rename. You can also directly drag and drop folders below, then click Next.

3. In the options interface, select position 9, because we need to insert text after "Project A" in "Project A Contract". Counting down, that is after the 9th character. If you need to insert text after a different character, you can click Help (see the image below for details). Enter the new text content you want to add below the insert text input field, and finally click Next. Then click Browse to select the save location for the new files.

4. Help: Here is the specific explanation, allowing precise control over which character position to insert text after. For example, 1 means to the right of the first character, -1 means to the right of the last character.

5. After the processing is finished, click the red path to open and view all successfully renamed folders.

Method 2: Use PowerShell Script to Batch Add Text in the Middle of Folders
Recommendation Index: ★★★☆☆
Advantages:
- Built-in PowerShell in the Windows system, usable without downloading or installing any third-party tools.
- Directly calls system APIs, resulting in high execution efficiency, can quickly process a large number of folders, and easily integrates into other system management tasks.
Disadvantages:
- Requires learning PowerShell scripting syntax and commands, posing a learning curve for average users.
- Folder names containing Chinese characters, spaces, or special symbols require additional encoding processing, otherwise errors may occur.
Operation Steps:
1. In the folder containing the folders you need to rename, Shift + Right-click to open PowerShell.

2. Enter the script below: The 3 below indicates the insertion position, and the blue text indicates the text to be inserted (you need to enter it yourself).

3. Press Enter to execute.
Method 3: Manually Rename to Batch Modify Folder Names
Recommendation Index: ★☆☆☆☆
Advantages:
- Each folder is operated individually, which is safe with zero risk and prevents batch errors.
- You see the new name as you type, getting an instant preview of the effect, and confirm only when satisfied.
Disadvantages:
- Efficiency is very low; handling 10 folders takes several minutes, and over 100 is extremely difficult.
- Prone to fatigue, and fatigue leads to errors, resulting in inconsistent insertion positions.
Operation Steps:
1. Select a folder and enter rename mode.

2. Position the cursor at the insertion location and directly type the new text.

3. Press Enter to confirm, then repeat the operation for other folders.
