Cant load file with spaces System.Io error

discovered this was apparently a package bug. worked fine using Nuget package DocX

Im trying to read in a file from a folder and save it as a different extension. What is the correct way to handle this? I read through the folder and encounter file paths like:

C:\Users\xx\Desktop_REPOS\scraper\Reading Questions\Week 1\239523-1094170 - yyy - Aug 24, 2017 148 PM - Short Answer Aug 21.docx

Error in my code

FileLoadException: Could not load file or assembly 'System.IO.Packaging, Version=4.0.2.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

I tried the solution from this post and got this error

System.IO.IOException: 'The filename, directory name, or volume label syntax is incorrect : 'C:\Users\king\Desktop_REPOS\scraper\scraper\bin\Debug\netcoreapp2.1\"C:\Users\king\Desktop_REPOS\scraper\Reading Questions\Week 1\239523-1094170 - yyy - Aug 24, 2017 148 PM - Short Answer Aug 21.docx"''

Mycode Code example I used

foreach (string path in Directory.EnumerateFiles(@"C:\Users\xx\Desktop\_REPOS\scraper\Reading Questions\Week 1", "*.*", SearchOption.AllDirectories)
.Where(s => s.EndsWith(".pdf") || s.EndsWith(".docx")))
{
        FileToTxt(path);
        //FileToTxt(AddQuotesIfRequired(path));
        Console.WriteLine("converted: " + Path.GetFileName(path));
}

public static void FileToTxt(string filepath)
{
    //Install-Package sautinsoft.document
    string textFilePath = Path.ChangeExtension(filepath, ".txt");
    DocumentCore docx = DocumentCore.Load(filepath); ////////---ERROR HERE
    docx.Save(textFilePath, SaveOptions.TxtDefault);
}

I wound up confirming this was a package bug and switched to using DocX

This was my final working solution:

    public static bool FileToTxt(string filepath)
    {
        try { 
        //Install-Package DocX
        string textFilePath = Path.ChangeExtension(filepath, ".txt");
        DocX docx = DocX.Load(filepath);
        File.WriteAllText(textFilePath, docx.Text);
        }catch(Exception e)
        {
            Console.WriteLine($"{Path.GetFileName(filepath)} error: {e.Message}");
            return false;
        }
        return true;
    }
