How to batch split TXT files? Split multiple Notepad documents by line count or specified number of parts

When multiple TXT Notepad files have long content and need to be split into several smaller files, copying, pasting, and saving them one by one is not only time-consuming but also prone to omitting content or disrupting the order. This article introduces how to use the text file splitting feature in office software to import multiple txt documents at once and process them in batches according to the maximum number of lines per file, the average number of split parts, or a custom range. In the example, 5 TXT files are each split evenly into 5 parts, and after processing, corresponding folders and numbered texts are automatically generated, which is suitable for scenarios such as log organization, data distribution, material archiving, and long-text segmentation.

In daily office work, it is common to encounter a batch of TXT Notepad files whose content is too long and needs to be split into multiple smaller files. For example, log text exported from a system needs to be analyzed section by section, large data lists need to be sent in batches, collected text materials need to be organized by line, or multiple long txt documents need to be split into a fixed number of parts and handed to different personnel for processing.

If there is only one file, manually copying and saving as a new file in Notepad may still be manageable; however, as the number of files increases, opening each file one by one, selecting content, copying, pasting, naming, and saving will generate a large amount of repetitive operations, and may also cause problems such as missing one line when copying, confusing file numbering, or inconsistent output locations. This article will take the office software HeSoft Doc Batch Tool as an example to explain how to import many TXT files at once and batch split each text file into multiple smaller files. The example uses the method of "split evenly into several files" to split 5 txt source files into 5 parts each.

1. Which scenarios are suitable for batch splitting TXT files

TXT splitting is not only about reducing file size; its more important value is to convert long text into smaller files that are easier to read, distribute, and process later. The following scenarios are especially suitable for batch processing:

• Log file segmentation: Server logs, software running records, or device data are saved in txt format. A single file has many lines and needs to be split for section-by-section inspection.
• Batching name lists and data lists: Split customer lists, numbering lists, keyword lists, test data, and so on into multiple text files by line count for convenient batch import into other systems.
• Long text collaboration: Divide multiple long texts evenly into several parts and assign them to different personnel for proofreading, annotation, or review, reducing manual splitting time.
• Data archiving: Split large or lengthy Notepad documents into smaller files and store them separately according to the original files for easier search and backup.
• Batch generation of test files: Development, testing, or data processing personnel need to quickly split multiple txt source data files into a fixed number of small samples.

Compared with processing one by one, the batch splitting function of office software allows multiple source files to share the same splitting rules. Users only need to add files in one place, set parameters once, then uniformly select a save location and start processing, which can significantly reduce repetitive work.

2. Preview of results: what changes before and after splitting multiple long TXT files

1. Before processing: multiple independent TXT documents are stored in the folder

In the sample directory before processing, there are 5 txt files, named big_bang.txt, black_holes.txt, dark_energy.txt, dark_matter.txt, and galaxies.txt. They are all source texts that need to be split, and each file contains its own complete content.

If the manual method is used, it is necessary to open these 5 files in turn, and then repeat content selection, new document creation, and numbered saving for each file. The more files and the more split parts, the more operations are required. For example, in this case, each source file needs to be split into 5 parts, resulting in 25 small text files, so the manual workload is not low.

2. After processing: corresponding folders are created according to the original file names

After batch splitting is completed, it can be seen that the output results are distinguished according to the source files, forming corresponding folders such as big_bang, black_holes, dark_energy, dark_matter, and galaxies. Open one of the folders, and you can see split results such as 1.txt, 2.txt, 3.txt, 4.txt, and 5.txt.

This result structure has two direct benefits: first, content split from different source files will not be mixed together, making it easy to confirm which original txt each group of small files comes from; second, the split files use continuous numbering, making it easier to maintain order during subsequent viewing, transfer, or further batch processing. The screenshot shows the result of splitting evenly into 5 files, so each original text corresponds to a group of 5 small files.

3. Steps for batch splitting many TXT Notepad files into small files

Step 1: Enter the "Split text file into multiple files" function

Open HeSoft Doc Batch Tool , and in the left-side function categories, enter "Text Tools". Then switch to the "Merge and Split" category, find and select "Split text file into multiple files". The purpose of this function is to batch process text files into multiple independent files according to line count or split quantity.

Entering the correct function page is the foundation of the entire operation. It should be noted that this task is to split each TXT into several small files, not to merge multiple txt files into one file, so "Split text file into multiple files" should be selected, and other functions such as "Merge text files into one file" should not be mistakenly selected.

Step 2: Add all TXT files to be processed at once

After entering the processing page, the first stage is "Select records to process". If only a small number of files need to be added, you can click "Add Files"; if the txt documents to be processed are already stored in the same directory, you can also use "Import files from folder" to reduce the operation of selecting files one by one.

After the files are imported, the page list will display information such as serial number, name, path, extension, creation time, and modification time. In this example, 5 records were successfully added, and all extensions are txt. At this point, it is recommended to check the following first:

1. Whether the number of files in the list is consistent with the actual number to be processed;
2. Whether the file names and paths are correct, to avoid mistakenly selecting files with the same name in other directories;
3. Whether the extension is txt, to ensure that the added files are the text files to be split in this task;
4. Whether there are records that do not need to be processed. If any, they can be removed through the delete operation on the right side of the list.

After checking, click "Next" to enter split rule settings. The significance of batch import is that the subsequent rules can be applied to multiple text files in the list at once, without the need to create a task repeatedly for each file.

Step 3: Select the TXT splitting method and fill in parameters

On the "Set processing options" page, three splitting methods can be seen: "Maximum number of lines per text file", "Split evenly into several files", and "Custom range splitting". The appropriate method should be selected according to the actual goal.

In this example, "Split evenly into several files" is selected, and 5 is entered below. It means that each source TXT in the list will be processed separately, with the goal of splitting each text evenly into 5 small files. In the previous result image, the output folder corresponding to each original file contains 1.txt to 5.txt, which is exactly the result of this parameter setting.

The three methods suit different needs:

• Maximum number of lines per text file: Suitable for tasks with a clear upper limit on the line count of a single output file. For example, when a data import platform limits the number of records per batch, splitting by maximum line count may be preferred.
• Split evenly into several files: Suitable for scenarios where the required number of results is already clear, such as dividing each text among 5 people for processing, or evenly dividing each source data file into fixed batches.
• Custom range splitting: Suitable for cases where text needs to be extracted by specified content ranges. When actually setting it, the range input rules provided on the software page should prevail.

After filling in the parameters, do not rush to continue. It is recommended to confirm the value again. The "5" here is the number of parts each source file should be evenly split into, not that all source files together produce only 5 results. If 5 source files are imported and each file is successfully split into 5 parts, the expected result is 5 groups of split results.

Step 4: Set the save location for split results

After confirming the parameters, click "Next" to enter the "Set save location" stage indicated in the process. Select the directory used to store the results according to the page prompts. For easier checking, it is recommended to separate the output directory from the source file directory, for example by creating a separate "TXT split results" folder.

Saving output results independently can avoid mixing original files with the smaller split files, and also makes it convenient to check the number of files by folder after processing. When selecting a directory, you should also confirm that the disk location can be written to normally and reserve enough storage space. Although splitting usually does not suddenly create a large amount of extra text content, multiple source files will generate more files and subdirectories, so the save path must be usable.

Step 5: Start batch processing and check the results

After setting the save location, enter the "Start processing" stage and start the task according to the page prompts. The software will process multiple txt documents in sequence according to the imported file list and the uniformly set split parameters. Unlike manual splitting, this process does not require repeatedly opening Notepad, copying content, or performing save-as operations one by one.

After processing is completed, open the output directory for spot checking. Focus on confirming: whether each source file has a corresponding result directory, whether each group of numbered files is complete, whether the split txt files can be opened normally, and whether the beginning and end content meet expectations. If the results are to be used for formal archiving or data import, it is recommended to test the rules with a small number of files first and confirm that the results are correct before processing the entire batch.

4. How to choose between splitting by line count or by number of parts

Many users hesitate about whether to split text by line count or by number of parts. The method of judgment is not complicated. The key is to see whether the subsequent task focuses on "how large each file is" or "how many final parts are needed".

If the receiving system stipulates that each txt can contain at most a fixed number of records, or each line represents one piece of data, then "Maximum number of lines per text file" is more suitable. It can split based on the upper limit of line count for a single output file, but the final number of generated parts will be affected by the total line count of the source file.

If the subsequent work needs to be distributed to a fixed number of people, devices, or batches, then "Split evenly into several files" can be used. This method targets the number of output parts. For example, if it is set to 5, it will try to divide each source text evenly into 5 parts. Since the total number of lines in the text may not be divisible by the number of parts, the actual line counts of the smaller files may differ slightly, which is normal in even splitting.

If you only want to extract a specified section instead of dividing evenly by a uniform line count or fixed number of parts, you can consider "Custom range splitting". Before choosing it, you should first clarify the line structure of the source text and fill in the ranges according to the software interface requirements to avoid missing or duplicated intervals.

5. Common questions and operational precautions

1. Will the software mix all TXT files together before splitting them?

From the result of this example, it can be seen that multiple source txt files are processed separately. After processing, corresponding folders are formed according to the original file names such as big_bang and black_holes, and smaller files such as 1.txt and 2.txt are saved in each directory. Therefore, the goal of this operation is not to merge all content first, but to apply the same splitting rules separately to each text in the imported list.

2. After setting "split evenly into 5 files", will the line count of each part definitely be exactly the same?

Not necessarily. If the total line count of the source text cannot be divided evenly by 5, the result files may differ by a small number of lines. Even splitting focuses on forming the specified number of parts as evenly as possible, rather than guaranteeing that the line counts of all files are completely identical in every case. If the business requires that each output file must not exceed a fixed line count, "Maximum number of lines per text file" should be used instead.

3. Why is it recommended to test with a small number of TXT files first?

Different texts may differ in content length, blank lines, and actual usage. First select one or two representative files for testing to help confirm whether the splitting method, parameter values, and save directory meet requirements. After confirmation, importing a large number of files can reduce the cost of reprocessing the entire batch after incorrect parameters are entered.

4. Do I need to back up the original files before splitting?

For important materials, it is recommended to keep the original txt files and save the results to a new directory. In this way, even if the split parameters need to be adjusted, the complete source files can still be used for reprocessing. Do not delete the original documents before checking the output content.

5. What should I do if file names are the same or results already exist in the save directory?

Before batch operations, check the source file names and whether there are already folders or numbered texts with the same names in the target directory. To avoid difficulty in distinguishing old and new results, you can create an independent output directory for each task and include the project, batch, or date in the directory name. As for how same-name results are specifically handled, the actual prompts of the software should prevail. Do not directly overwrite important materials without confirmation.

6. How should split files be checked and accepted?

It is recommended to check at least three aspects: first, whether the number of source files corresponds to the number of output result groups; second, whether the number of files generated in each group meets the settings; third, randomly open the first, last, and middle files of each group to see whether the text displays normally and whether the content connection meets usage requirements. For txt files containing important business data, you can also record the total line counts before and after processing and compare them.

6. Summary

The core of batch splitting TXT files is to convert the repetitive operations that originally required opening Notepad one by one into a standard process of "importing files centrally, setting rules uniformly, saving uniformly, and executing in batches". Using HeSoft Doc Batch Tool , you can add many txt texts at once and choose to split them by maximum line count, even number of parts, or custom ranges according to the task requirements.

In this example, 5 source TXT files were each split evenly into 5 small files. After processing, corresponding directories were created according to the original file names, and the split results were saved with continuous numbering. This method can both keep texts from different sources independent of each other and facilitate subsequent distribution, checking, and archiving.

If you are manually splitting a large number of logs, name lists, data lists, or lengthy Notepad documents, you can first organize the source files and keep backups, then enter "Text Tools - Merge and Split - Split text file into multiple files" in the software, confirm the parameters with a small number of samples, and finally execute batch processing. This can reduce copy-paste and repeated save-as operations, leaving more time for the work that truly requires judgment and review.
