When a large number of file names have fixed-length English prefixes, number prefixes, or useless identifiers on the left side, manually renaming them one by one is very time-consuming and prone to omissions or accidental deletions. This article uses HeSoft Doc Batch Tool as an example to demonstrate how to use the file name processing feature in office software to batch delete the first few characters on the left side of file names. In the example, the first 5 characters of files such as Alpha2024010101.docx and Bravo2024020202.doc will be removed, retaining the subsequent date numbers and original extensions. This applies to Word, Excel, PPT, PDF, image, text, and other file types.
In daily office work, we often encounter the problem of inconsistent file name formats. For example, exported materials, archived contracts, and attachments sent by clients may have file names preceded by English words, department codes, project abbreviations, or temporary identifiers, while the actual content that needs to be retained is the date, number, or file subject at the end. If there are only a few files, manual renaming is acceptable; but if there are dozens, hundreds, or even more files, deleting the leftmost characters one by one is not only repetitive but also prone to accidentally deleting part of the file name.
The problem addressed in this article is very specific: how to batch delete a certain number of text characters from the far left of file names. Here, "the leftmost few characters" can be understood as a fixed number of characters at the beginning of the file name. For instance, deleting the leftmost 5 characters from Alpha2024010101.docx results in 2024010101.docx, and deleting the leftmost 5 characters from Bravo2024020202.doc results in 2024020202.doc. This entire process is suitable for handling various file types such as docx, doc, pptx, ppt, xlsx, xls, pdf, jpg, txt, and csv.
Below, we will use HeSoft Doc Batch Tool for demonstration, accompanied by screenshots. It is a batch document processing software designed for office scenarios, and its core value lies in consolidating repetitive manual tasks like file organization, file name processing, and document batch processing, thereby reducing redundant labor and improving file management efficiency.
Applicable Scenarios: When do you need to batch delete characters from the left side of a file name?
Batch deleting the leftmost few characters from a file name is common in the following office scenarios:
Removing fixed-length English prefixes: For example, files like Alpha2024010101.docx, Bravo2024020202.doc, and Chart2024030303.pptx, where the English at the beginning is only a temporary classification or source identifier, and the subsequent numeric code is the formal file name.
Removing prefixes automatically added by export systems: When exporting files from certain business, reporting, or OA systems, a fixed-length project code or batch identifier is appended to the left side of the file name, which needs to be uniformly deleted during subsequent archiving.
Organizing mixed Word, Excel, PPT, and PDF files: A batch of materials may simultaneously contain docx, doc, xlsx, xls, pptx, ppt, pdf, txt, jpg, and other files. If their naming rules are consistent, they can be processed in one go instead of being manually renamed by file type.
Standardizing historical file naming conventions: Older file names might contain meaningless personnel codes, English abbreviations, or department prefixes. For better future retrieval and sorting, these starting characters can be batch removed.
Batch retaining date codes: Many file names use a "prefix + date code" structure, for example, Eagle2024050505.xlsx. After deleting the left-side prefix, the remaining 2024050505.xlsx is more suitable for chronological sorting and archiving.
It is important to note that the method demonstrated here applies when "the number of characters to delete is fixed." This means the same number of characters is deleted from the left side of every file name. In the example, the leftmost 5 characters are deleted.
Effect Preview: File names contain English prefixes before processing
Before processing, the file names in the folder all contain an English word prefix on the left side, followed by a date-based numeric code, while the file extensions retain their respective types. For example, Alpha2024010101.docx, Bravo2024020202.doc, Chart2024030303.pptx, Delta2024040404.ppt, Eagle2024050505.xlsx, etc. The positions marked in red indicate the left-side text that needs to be deleted.
As can be seen from the screenshot, this batch of files is not limited to just one format but includes various types such as Word documents, PowerPoint presentations, Excel spreadsheets, images, text files, PDFs, and CSVs. For such a mix of files, renaming them one by one is prone to problems like missing some files or accidentally deleting file extensions. Using a batch renaming tool allows the processing rules to be applied uniformly to all files.
Effect Preview: Only the following number and extension are retained after processing
After processing is complete, the English parts at the beginning of the file names have been deleted, preserving the date codes and file extensions that were originally located at the end. For example, Alpha2024010101.docx becomes 2024010101.docx, Bravo2024020202.doc becomes 2024020202.doc, and Chart2024030303.pptx becomes 2024030303.pptx. The file types remain unchanged, with extensions still being docx, doc, pptx, ppt, xlsx, xls, jpg, txt, pdf, csv.
This result shows that the batch deletion targets the text on the left side of the main file name, without altering the file content or converting the file format. This is crucial for daily file organization: we only want to change the name, and do not wish to affect the opening and use of Word, Excel, PPT, PDF, and other files.
Operation Steps: Using office software to batch delete the 5 leftmost characters from file names
Below is a complete explanation of the operation process, following the order of the software interface screenshots. The example software is HeSoft Doc Batch Tool . On the left side of the interface, you can see the "File Name" category, which contains various file name processing capabilities. The function we need to use is "Delete text from file names."
Step 1: Enter the "File Name" category and select the delete file name text function
After opening HeSoft Doc Batch Tool , locate the "File Name" category in the left navigation bar. This category displays multiple functions related to batch renaming, such as finding and replacing keywords in file names, inserting text into file names, and adding prefixes and suffixes to file names. Our goal this time is to delete a segment of text from the file names, so we select the 10th item, "Delete text from file names."
The purpose of this step is to enter the dedicated configuration page for file name deletion rules. After selecting the correct function, the software will enter a step-by-step processing interface where you can subsequently add files to process, set deletion rules, specify the save location, and start processing.
Step 2: Add the files to be processed and confirm the file list
After entering the "Delete text from file names" page, you will see buttons at the top of the interface like "Add Files," "Import files from folder," "Clear," and "More." If you only need to process a few specific files, you can use "Add Files"; if all files are in the same folder, using "Import files from folder" is more suitable.
After the files are imported, the software displays information in the list such as sequence number, name, path, extension, creation time, and modification time. The example shows 10 records, with file names including Alpha2024010101.docx, Bravo2024020202.doc, Chart2024030303.pptx, Delta2024040404.ppt, Eagle2024050505.xlsx, Frame2024060606.xls, Graph2024070707.jpg, Hotel2024080808.txt, Index2024090909.pdf, and Judge2024101010.csv.
In this step, it is recommended to check two key points: first, whether all files have been imported; second, whether any files that do not need processing have been included. There is a delete operation icon on the right side of the list; if you find that a certain file does not need to participate in this batch renaming, you can remove it from the pending list first. After confirming everything is correct, click "Next" at the bottom of the interface.
Step 3: Set processing options, choose to delete "the first few characters on the left"
After entering the processing options page, you will see multiple operation types, such as all numbers, all whitespace, all Chinese characters, all content, all content to the left of a certain text string, a position range, all English letters, the first few characters on the left, and all content to the right of a certain text string. Because this example requires deleting a fixed number of characters from the beginning of each file name, we select "the first few characters on the left."
After selecting the operation type, you need to enter the number of characters to delete in the "Count" input box. In the example, 5 is entered, indicating the deletion of 5 characters starting from the far left of the file name. Taking Alpha2024010101.docx as an example, Alpha is exactly 5 English letters, and after deletion, 2024010101.docx remains; for Bravo2024020202.doc, Bravo is also 5 English letters, and after deletion, 2024020202.doc remains.
Click "Next" after completing the settings. The expected result of this step is that the software has recorded the batch deletion rule: delete 5 characters from the far left for each file name in the list.
Step 4: Set the save location to avoid the risk of overwriting
The third step in the interface flow is "Set save location." Following the conventional workflow for batch processing office files, it is advisable to confirm the output location before the formal processing begins. If the software offers a choice between saving to the original location or saving to a designated location, the decision should be made based on the importance of the files. For first-time batch processing, large numbers of files, or situations where file naming rules are not fully confirmed, it is best to save to a new folder first for easier result verification.
The purpose of this operational step is to have a clear storage location for the processed files, avoiding confusion with the original files. Especially when dealing with important contracts, reports, client materials, or project documents, it is safer to keep the original files first and then check the processing results.
Step 5: Start processing and check the results
After completing the save location settings, enter the "Start Processing" step. After clicking the start button, the software will batch rename the files according to the rules set earlier. Once processing is complete, open the output folder or the original folder for verification, confirming that the leftmost 5 characters of each file have been deleted and that the file extensions remain unchanged.
Looking at the screenshot after processing, it can be seen that the original English prefixes have disappeared and the file names are now uniformly in a date-number format. This indicates that the task of batch deleting the leftmost characters from the file names has been completed.
Frequently Asked Questions and Precautions
1. How should the number of characters to delete be determined?
The number of characters to delete should be determined based on the number of characters that need to be removed from the far left of the file name. In the example, Alpha, Bravo, Chart, Delta, Eagle, Frame, Graph, Hotel, Index, and Judge are all 5 English letters, so the count is filled in as 5. If your file name prefix is something like "ABC_" which is 4 characters, you should fill in 4 based on the actual length.
2. Will the file extension be deleted?
Based on the example results, the extensions like docx, doc, pptx, ppt, xlsx, xls, jpg, txt, pdf, and csv were all retained after processing. In other words, the target of this operation is the text within the file name, not the file format. However, during the actual operation, it is still recommended to spot-check a few files after processing to confirm they can be opened normally.
3. What if the prefix lengths in the file names are inconsistent?
If the number of characters to be deleted from the left side of each file name varies, using a fixed number of deletions is not suitable. For example, some prefixes might be ABC, others Alpha, and others Department. Forcefully deleting the same number of characters could accidentally remove valid content that follows. In such cases, you should first organize the naming rules or choose a more appropriate method from other operation types offered by the software.
4. Should you back up files before batch renaming?
Backing up is recommended. Batch file name processing is highly efficient, but this also means an erroneous rule can affect multiple files at once. Before formal processing, you can first copy a test folder or import a small number of files for a trial run to confirm the rules are correct before processing all files.
5. Which file types are suitable for this processing?
Any common office files that require a name change can be processed according to the rules. The example includes Word's docx and doc, Excel's xlsx and xls, PowerPoint's pptx and ppt, as well as pdf, jpg, txt, csv, and others. The key factor is not the internal file content format, but whether the file name conforms to the batch processing rules.
Summary: Let batch processing tools handle repetitive renaming
Batch deleting the leftmost few characters from file names is a very typical, high-frequency need in file organization. Manual renaming seems simple, but as the number of files increases, it consumes a lot of time and is prone to issues like missed changes, accidental deletions, and damaged extensions. Using office software like HeSoft Doc Batch Tool can standardize the process of "selecting files, setting rules, and executing batch tasks," completing the unified renaming of various file formats in one go.
If your files also have fixed-length prefixes, such as English words, project codes, department identifiers, or system-exported numbers, you can follow the steps in this article: enter the file name category, select "Delete text from file names," import files, choose "the first few characters on the left," fill in the count, set the save location, and start processing. It is recommended to test with a small number of files first to ensure the results are correct before batch processing all materials. This approach can both enhance efficiency and ensure the accuracy of file organization.
