Based on your issue, it looks like Aspose.Words.FileFormatUtil.DetectFileFormat is not detecting the text file correctly. The file extension .txt is supported by Aspose.Words and typically supports plain text files. Here’s a step-by-step guide to troubleshoot this issue:

Steps to Reproduce the Issue

  1. Unzip the attachment:

    • Unzip the data_1000chars_Uknown.txt.zip file to extract data_1000chars_Uknown.txt.

  2. Call the method:

    Aspose.Words.FileFormatUtil.DetectFileFormat("path_to_your_extracted_file");

Expected Result

The expected result is to detect the file format as “Txt,” but it is detected as “Unknown.”

Troubleshooting Guide

  1. Verify the File Content:

    • Ensure that the file data_1000chars_Uknown.txt contains plain text without any encoded data or corruption.
    • Open it with a text editor to check the content.

  2. Verify Aspose Product Version:

    • Ensure that you are using the latest version of Aspose.Words.
    • You can download the latest version or check for updates here.

  3. Check the File Path:

    • Ensure that the file path provided to the DetectFileFormat method is accurate and accessible.
    • You can use an absolute path to avoid any path-related issues.

  4. Run a Simplified Code:

    • Test with a simple code to ensure there are no external factors causing the issue.
    using Aspose.Words;

public class Program
{
    public static void Main()
    {
        string filePath = "C:\\path_to_your_file\\data_1000chars_Uknown.txt";
        Aspose.Words.FileFormatInfo formatInfo = FileFormatUtil.DetectFileFormat(filePath);
        Console.WriteLine(formatInfo.FileFormat);
    }
}

@Buffer2018 Actually any file can be considered as TXT document, to properly detect TXT format it is required to exclude other formats. TXT is kind of “last resort format” for a file.
Even if FileFormatUtil.DetectFileFormat cannot detect your document as TXT. You can load the document using the following code and it will be loaded as TXT:

Document doc = new Document(@"C:\Temp\in.txt");
Console.WriteLine(doc.OriginalLoadFormat);

i understand, but the functionality im looking here is to identify (with some kind of certainty) that a file contains text. the attached file is a plain UTF-8 text file, but still is detected as Unknown and not as Txt.
