Fix Word Error: File Name Not Valid in INCLUDETEXT Fields
Question details
The user needs to resolve an invalid file name error that occurs when utilizing INCLUDETEXT fields to insert external content into mail merge documents.
- Product
- Microsoft Word / WPS Writer
- Device & OS
- not provided
- Scenario
- Running a mail merge document that relies on an INCLUDETEXT field to dynamically pull in text or content from a separate external document file.
- Observed behavior
- Instead of displaying the content from the target file, the document displays the error message 'Error! File name not valid'.
Ensure you know the exact folder path of the document you are trying to include and verify that the target file is accessible on your computer.
Double the Backslashes in the File Path
The most common cause of this error is single backslashes in the Windows file path, which the word processor misinterprets as special switch codes rather than folder separators.
In field codes, a single backslash is considered an escape character used to trigger specific commands or switches. To specify a standard file path, you must escape the backslash itself by doubling it, or alternatively use single forward slashes.
Open your document and press Alt + F9 (or Alt + Fn + F9 on some laptop keyboards) to toggle the view from the error message to the actual field codes.
Find the INCLUDETEXT field that is causing the error. You will see a file path inside quotation marks, such as "C:\MyFolder\MyDocument.docx".
Edit the file path by changing every single backslash (\) to a double backslash (\\). The corrected path should look like "C:\\MyFolder\\MyDocument.docx".
Select the field and press F9 to update it, verifying the text now loads correctly. Once confirmed, run your mail merge process again.

Frequently Asked Questions
What does INCLUDETEXT do in a document?
The INCLUDETEXT field is used to insert the complete contents of one document into another. It is highly useful for mail merges, templates, and dynamic reports where standard text blocks need to be pulled from a master file.
Are there other ways to format the file path in INCLUDETEXT besides double backslashes?
Yes. Alternatively, you can use single forward slashes (/) instead of double backslashes (e.g., "C:/MyFolder/MyDocument.docx"). The field code engine parses forward slashes correctly as directory separators.
Why didn't updating the field fix my document?
If doubling the backslashes does not resolve the issue, check that the file path is completely correct, the target file hasn't been moved or renamed, and that the entire path is enclosed within standard straight quotation marks (not smart quotes).
How do I update a specific field without updating the whole document?
Simply click or highlight the specific field you want to refresh, then right-click and choose 'Update Field', or press the F9 key on your keyboard.
