try the below code only for reference use only
using System;
using System.IO;

class Test
{
    public static void Main()
    {
        string resumeFile = @"c:\ResumesArchive\923823.txt";
        string newFile = @"c:\ResumesImport\newResume.txt";
        if (File.Exists(resumeFile))
        {
            File.Copy(resumeFile, newFile);
        }
        else
        {
            Console.WriteLine("Resume file does not exist.");
        }
    }
}

Hi,

You need to use Server.MapPath

if (File.Exists(Server.MapPath(wordDocName)))

*Note - Also check you have
necessary permissions for read or not

I hope it's just server shared network path. Then below code will work.
FileInfo fi = new FileInfo(@"\\server\share\file.txt");
bool exists = fi.Exists;

On server you have to use File.Exists(Server.MqpPath(txtpath.Text));
