If materials are saved in categorized folders, and each folder contains multiple PDFs, merging them manually one by one would be very inefficient. This article explains how to use the PDF tool in HeSoft Doc Batch Tool to batch merge PDFs by folder: select "Merge multiple PDF folders into multiple files", add the target folders, set the merge order by name ascending or descending, then set the save location and start processing. The example demonstrates the complete effect from multiple PDF files to a single Test folder 4.pdf, suitable for batch archiving, material organization, and file submission scenarios.
Many office documents are not stored as individual files, but are organized into folders. For example, one folder per client, one folder per project, one folder per course, or one folder per scanning task. Each folder might contain multiple PDF files: contract bodies, appendices, manuals, invoices, reports, chapter materials, etc. When it's time to submit or archive, we often prefer "one folder ended up as one PDF", which makes searching, sending, and saving much clearer.
If you only do it once, merging PDFs manually might be acceptable; but if you need to organize multiple folders every day, repeatedly opening files, importing files, adjusting order, and saving as PDF becomes a very clear inefficient operation. This article focuses on the practical need of "batch merging PDF files by folder" and explains how to use the office software " HeSoft Doc Batch Tool " to merge multiple PDFs within a folder into a single PDF file. In the example, the folder contained multiple PDFs before processing, and after processing, a merged result named Test folder 4.pdf was generated.
Applicable Scenarios: Organizing PDFs by Folder is More Efficient than Merging Files Individually
The approach of merging PDFs by folder is especially suitable for scenarios where materials are already stored in categorized folders. It does not require the user to pick PDFs one by one; instead, the user directly selects a folder, and the software reads the PDFs inside the folder and generates the corresponding merged file.
Client material organization: One folder per client, containing PDFs like business licenses, contracts, quotations, and statements. After merging, each client gets a single comprehensive PDF document.
Project document archiving: Proposals, meeting minutes, acceptance documents, and supplementary materials generated during a project are scattered in the same directory. Through folder-based PDF merging, a project archive suitable for long-term preservation can be formed.
Scan file aggregation: Scanners or mobile scanning apps often output multiple PDFs per batch. Using a batch processing tool, the same batch of scans can be merged into one complete PDF, avoiding scattered page numbering.
Learning material integration: Multiple English materials, papers, handouts, or chapter PDFs stored in one folder can be merged and read continuously like an e-book.
Multi-folder batch processing: When materials are already categorized into multiple folders, you can use features like "Merge Multiple PDF Folders into Multiple Files" to generate one PDF for each folder respectively. This article demonstrates with a single folder; once mastered, the operation can be extended to batch processing of multiple folders.
Effect Preview: From Scattered PDFs to a Single Merged PDF
Before processing, the example folder Test folder 4 contained multiple PDF files. As seen in the screenshot, filenames include human-exploration.pdf, Learn_English_in_an_easy_fast_and_fun_way..., learning-tips.pdf, SampleContract-Shuttle.pdf, The Safety of Mars Sample Return.pdf, the-crowdsourced-guide-to-learning.pdf, Voyager-Grand-Tour.pdf, etc. The right side shows the size of each PDF, indicating they are still multiple independent files.
In this state, if you need to send the materials to someone else, you would have to send multiple attachments; if archiving, you need to ensure none of the files are missed. The more files there are, the higher the management cost.
After the merging process, the output result becomes a single PDF file: Test folder 4.pdf. The screenshot shows this file size is 12,440 KB. In other words, the multiple PDFs in the original folder have been merged into one new PDF document, and subsequently, only this one file needs to be managed.
From the perspective of questions frequently searched by users, this is the typical answer to needs like "how to merge multiple PDFs into one," "how to batch merge PDFs in a folder," and "how to use a PDF folder merge tool": use office software that supports batch folder processing to complete the merge on a per-folder basis.
Operation Steps: Merging a PDF Folder into One PDF
Below, taking HeSoft Doc Batch Tool as an example, the specific operations are explained according to the screenshot sequence. This software is positioned as a document batch processing office tool, suitable for reducing inefficient operations like repeated clicking, repeated selections, and repeated saving.
Step 1: Find the Folder Merge Function in the PDF Tool
After launching HeSoft Doc Batch Tool , first look at the function navigation on the left. The interface includes categories such as Home, Task Flow, All Tools, File Name, Folder Name, File Organization, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, etc. To handle the PDF merge task, you need to click PDF Tools on the left.
In the PDF tools list, find "Merge Multiple PDF Folders into Multiple Files". In the screenshot, this function card is highlighted with a red box, indicating it is the entry point for this operation. The description for this function shows it is used for batch merging many folders containing PDFs into multiple independent PDF files.
The key point of this step is choosing the right function. If you only want to convert PDF to Word or PDF to Excel, you should select a conversion function; if your goal is to aggregate multiple PDFs in a folder into one PDF, you should go to the "PDF Folder Merge" related function.
Step 2: Click "Add Folder" and Select the Directory Containing PDFs
After entering the function page, the top displays the current task name "Merge Multiple PDF Folders into Multiple Files". The upper right corner of the page has "Add Folder", Clear, More, and other operation buttons. Click "Add Folder" at this time and select the directory where the PDFs to be merged are located.
The screenshot shows a folder named Test folder 4 has been added. The list displays the folder's path, creation time, and modification time. This information confirms that the software has received the correct processing target.
The purpose of adding a folder is to tell the software "which batch of PDFs to process." Compared to adding PDF files one by one, adding by folder is more suitable for batch office work: as long as the PDFs to be merged are already placed in the folder, there is no need to check files individually.
If you need to process multiple folders, you can continue adding other folders; if you only process a single directory like this article's example, just confirm that the list contains only the target folder. After confirming it's correct, click "Next" at the bottom.
Step 3: Choose to Merge in Ascending or Descending Order by Name
After entering the second stage "Set processing options", the interface provides "Sorting method". The screenshot shows two single options: Merge in ascending order by name and Merge in descending order by name. Currently selected is Merge in ascending order by name.
The sorting method affects the page arrangement order in the merged PDF. For example, if a folder contains 01-Cover.pdf, 02-Table of Contents.pdf, 03-Body.pdf, 04-Appendix.pdf, choosing to merge in ascending order by name will arrange the merged PDF in the order 01, 02, 03, 04, which is more in line with reading habits.
If your files are named according to Z to A, reverse date order, or other reverse rules, you can choose to merge in descending order by name. Regardless of the choice, it is recommended to browse the filenames in the folder before processing to confirm the naming rule matches your desired merge order.
For scans and chapter materials, it is especially recommended to use numeric prefixes. Avoid using filenames without sequential meaning like "New Document," "Scan File," or "Copy," otherwise the order might need readjustment after merging.
Step 4: Enter Save Location Settings to Determine the Output Directory
After completing the sorting method setting, click "Next". According to the interface flow, the next stage is Set save location. This step is used to determine where the merged PDF file will be saved.
In actual office work, it's recommended that the output directory follow two principles: first, it should be easy to find; second, it should be easy to distinguish between original files and processing results. For example, you can create a new "PDF Merge Results" folder specifically to save the generated PDFs. This way, original materials are neither overwritten nor confused, and subsequent result checking is facilitated.
If you are processing multiple client or project folders, setting a unified output location makes centralized viewing more convenient. The generated PDFs can usually be identified based on the source folder name. In the example, the source folder is Test folder 4, and the final result is Test folder 4.pdf, showing a clear name correspondence.
Step 5: Start Processing to Generate the Merged PDF File
After completing the save location setting, enter the final "Start Processing" stage. Once the task is executed following the interface prompts, the software will automatically read the PDF files in the target folder and merge them according to the previously selected sorting method.
After processing is complete, open the output directory to view the result. In the example, multiple PDF files eventually generated Test folder 4.pdf. It is recommended to open the merged PDF on first use to check several items: whether the pages are complete, whether the order is correct, whether the file can be opened normally, and whether the filename meets archiving requirements.
If the check results meet expectations, this merged PDF can be used for sending, uploading, archiving, or printing. Compared to manual merging, the entire process is more suitable for repetitive office tasks, especially for users who need to frequently organize PDF folders.
Common Questions or Precautions
1. How many PDFs will be generated from one folder?
According to the usage logic of this function, one folder containing PDFs will be merged to generate one PDF file. If multiple folders are added, each folder generates its corresponding PDF file respectively. This is also the meaning behind the function name "Merge Multiple PDF Folders into Multiple Files".
2. What happens to non-PDF files in the folder?
The function demonstrated in this article is designed for processing PDF folders, so it is recommended to place mainly the PDF files to be merged in the target folder. To reduce interference, you can move unrelated files out before merging to keep the directory clean.
3. Should I rename PDFs before merging?
Renaming is recommended, especially for materials with sequential requirements. Because the sorting method provided in the screenshot is merging in ascending or descending order by name, filenames directly affect the merge order. Using numeric prefixes like 01, 02, 03 is a relatively safe practice.
4. Why is the merged PDF named after the folder?
From the processing result screenshot, it can be seen that the source folder Test folder 4 generated Test folder 4.pdf after merging. This naming method makes it easy to identify the relationship between the result and the source folder, especially making management easier during batch processing of multiple folders.
5. Do I need to keep the original multiple PDFs?
It is recommended to keep the original files at least until you confirm the merged result is correct. The merged PDF is suitable for sending and archiving, while the original PDFs can serve as backups, facilitating subsequent reprocessing or finding a specific document individually.
6. Is it normal for the file size to become 12,440 KB?
This is normal. The merged PDF contains the content of multiple original PDFs, so the file size usually increases. In the example, multiple independent PDFs merged to generate a 12,440 KB Test folder 4.pdf, which is a common characteristic of merged files.
Summary: Merging PDFs by Folder Brings More Order to Document Organization
Merging multiple PDF files into a single PDF essentially reduces file management costs. Especially when materials are already categorized by folder, using office software that supports batch processing is more efficient than manually selecting files one by one. The "Merge Multiple PDF Folders into Multiple Files" function in HeSoft Doc Batch Tool is suitable for merging one or multiple PDF folders into independent PDFs respectively, helping users reduce repetitive operations.
In practical use, you can follow the process in this article: first enter PDF Tools, select the folder merge function; then join the target directory via "Add Folder"; next, choose to merge in ascending or descending order by name based on the file naming rule; finally, set the save location and start processing. Once complete, just check if the generated PDF is complete and the order is correct.
If you often deal with PDF folders for contract attachments, scans, learning materials, project files, etc., it is recommended to integrate this batch merging method into your daily office workflow. It allows scattered files to quickly become clearly structured single PDFs, reducing repetitive labor and making subsequent sending, archiving, and viewing more efficient.
