When there are multiple PDF files in a folder, manually merging them one by one is not only tedious but also prone to sequence errors. This article uses HeSoft Doc Batch Tool as an example to explain how to add a folder through a PDF tool, set the merge order by ascending or descending name, and batch merge multiple PDFs in the folder into a single PDF file, helping office users quickly complete document archiving and delivery.
Many people encounter the same issue when organizing PDF materials: all the files are neatly placed in a folder, yet they remain scattered individual PDF documents. When sending them to colleagues or clients, you have to attach each file one by one; for archiving, the file list appears cluttered; and when reading, you constantly need to switch between different documents. Contents like contract attachments, course materials, project documents, and scanned copies are often better organized into a single, complete PDF.
This article introduces a method suitable for office scenarios: using HeSoft Doc Batch Tool to batch merge multiple PDF files from a folder into one PDF file. Its core logic is to process by folder, allowing the software to automatically read the PDFs within a folder and generate a merged PDF according to a specified sorting order. For users looking to reduce repetitive work and improve file organization efficiency, this approach is more stable than manual, file-by-file operations.
Applicable Scenarios: When to Merge PDFs from a Folder
PDF merging is very common in office workflows, but different scenarios have different requirements for efficiency and accuracy. The following situations are particularly well-suited for using batch processing software:
- Submitting documents externally: For example, bidding documents, project descriptions, qualification certificates, and contract attachments often need to be organized into a single complete PDF for the recipient's convenience.
- Internal archiving: When departmental documents, meeting minutes, approval materials, and training documents are stored separately, merging them facilitates long-term preservation.
- Organizing scanned files: Multiple scans generating several PDFs that ultimately need to be combined into one complete scanned document.
- Study and research materials: Multiple PDF papers, chapters, or lecture notes placed in one folder become more coherent for reading after merging.
- Batch processing of material packages: When each client, project, or course has its own independent folder, you can batch generate corresponding PDFs per folder.
This tutorial focuses on demonstrating "one folder generates one PDF." If you face multiple similar folders in the future, you can apply the same logic for batch processing.
Result Preview: Changes in the Number of Files Before and After Merging
Before Merging: A Folder Containing Multiple Independent PDFs
In the screenshot before processing, the Windows folder Test folder 4 contains several PDF files. They each have different filenames and sizes, such as human-exploration.pdf, The Safety of Mars Sample Return.pdf, the-crowdsourced-guide-to-learning.pdf, etc.
Although these files are all in the same folder, they are still multiple independent PDFs. If you need to send or archive them uniformly, they must be merged into a single whole file.
After Merging: Output as a Single PDF File
The screenshot after processing shows that a PDF file named Test folder 4.pdf was ultimately created, with a size of 12,440 KB. This means the multiple PDFs in the original folder have been combined into one PDF.
The merged file name corresponds to the original folder name, making it more intuitive to find. For batch archiving, this naming convention can reduce the workload of manual renaming.
Operational Steps: Batch Merging PDFs from a Folder into One PDF
Step 1: Open the PDF Tools Category
After launching HeSoft Doc Batch Tool , you can see multiple office processing categories on the left, such as File Name, Folder Name, File Organization, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, etc. Since PDF files are being processed this time, click PDF Tools on the left.
In the PDF tools list, select "Merge multiple PDF folders into multiple files". In the screenshot, this function is highlighted with a red box and prompts that it can batch merge many folders containing PDFs into multiple independent PDF files.
It is crucial to understand a key point here: This function is not just for a single PDF, but for "folders containing PDFs." When you add a folder, it will merge the PDFs within that folder into a single file; when you add multiple folders, each folder will produce a corresponding PDF result.
Step 2: Add the Target Folders Containing PDFs
After entering the function page, the top of the interface displays the current function name as Merge multiple PDF folders into multiple files. In the upper right corner, there is an Add Folder button, which is the most important entry point for this step.
After clicking Add Folder, select the folder whose PDFs you need to merge. Once added, the folder will appear in the list, showing information including sequence number, name, path, creation time, modification time, and actions. In the screenshot, Test folder 4 has been added, with its path displayed as the corresponding folder on the desktop.
After confirming that the folders in the list are the target folders you intend to process, click the Next button at the bottom of the page. If an incorrect folder was added, you can delete the corresponding record through the action area in the list, or use the clear function on the page to re-add them.
Step 3: Choose to Merge by Name in Ascending or Descending Order
After entering the second process node, Set Processing Options, the software provides sorting method settings. In the screenshot, two radio options can be seen: Merge by Name Ascending and Merge by Name Descending.
If your file names follow a normal reading order, for example starting with 01, 02, 03, it is recommended to select Merge by Name Ascending. This ensures the page order in the output PDF better fits reading habits. If your file names need to be arranged from back to front, you can choose Merge by Name Descending.
The sorting setting seems simple, but it determines the content order of the final PDF. For formal documents like contracts, reports, and manuals, it is advisable to check the file names before merging to avoid situations where the cover page ends up last or attachments appear before the main text.
Step 4: Proceed to Set the Save Location
According to the flow at the top of the interface, after setting processing options, you will proceed to Set Save Location. This step specifies where the merged PDF file should be saved. It is recommended to choose an easily identifiable output directory, such as "PDF Merge Results" or "Merged PDFs."
This practice offers two advantages: it prevents mixing results with original PDFs, making comparison easier; and it facilitates later checking and copying. If the original PDFs still need to be kept, it is best not to repeatedly overwrite the processing results directly within the original folder.
Step 5: Start Processing and Review Results
After completing the settings, proceed to Start Processing. After execution, wait for the software to finish merging. Once processing is done, open the save location to see the generated PDF file. In the example, the output result is Test folder 4.pdf, indicating that the multiple PDFs within that folder have been successfully merged.
It is recommended to open the resulting PDF for a quick check: ensure pages are complete, the order is correct, and the file name meets archiving requirements. If the order is found to be incorrect, you can return to the original folder to adjust the file naming, then re-merge by name ascending or descending.
Frequently Asked Questions and Notes
1. What determines the merging order?
As visible from the screenshot, this function offers merging by name ascending and by name descending. Therefore, the file name is a key factor affecting the merging order. To obtain a stable result, it is recommended to add a numbered prefix to PDF files.
2. Why are folders added instead of PDF files?
This function is designed for batch merging PDF folders. After adding a folder, the software processes the PDFs within it folder-by-folder. This is more convenient for batch scenarios involving multiple project document packages or client material folders.
3. What if there are PDFs in the folder I don't want to merge?
Before adding a folder, it is recommended to clean the target folder first, keeping only the PDFs that need to participate in the merge. Since this function processes folders, unwanted PDFs mixed in the folder could affect the final result.
4. What is the output PDF name?
Judging from the example results, the output PDF name matches the original folder name, meaning the Test folder 4 generates Test folder 4.pdf. This method facilitates quick identification of the source for each result file after batch processing.
5. Is it suitable for a large volume of PDF materials?
This function is positioned for batch processing of office files, designed to reduce repeated adding, merging, and saving operations. If you frequently need to organize numerous PDF folders, using this batch method will be more efficient than manual merging.
Conclusion: Solving PDF Organization Challenges with a Batch Processing Approach
When a folder contains many PDFs, the most effective approach is not to open and process them individually, but to use office software that supports batch folder processing. With HeSoft Doc Batch Tool , you can enter PDF Tools, select "Merge multiple PDF folders into multiple files," add the target folders, set the merge order by name ascending or descending, proceed to set the save location, and start processing.
The entire workflow is clear and is particularly suitable for contract archiving, material compilation, scanned document organization, and project delivery. It is recommended that you standardize PDF file names before merging, and then use this function to batch generate the result files. This not only saves time but also makes the final PDF order more accurate and the archiving more standardized.
