            Console.ReadLine();
        }
    }

I have filenames like

Accounting Voucher  Display.pdf 196910351_0_03192019144415.xml

i need to check weather the given folder that this file are not.

File.Exists

returns always false.

Please find the below link there i was found the below lines

The Exists method returns false if any error occurs while trying to determine if the specified file exists. This can occur in situations that raise exceptions such as passing a file name with invalid characters or too many characters, a failing or missing disk, or if the caller does not have permission to read the file.

You appear to have different numbers of spaces in your file names.

Works for me:

C#

string path = @"D:\Test Data\Accounting Voucher  Display.pdf 196910351_0_03192019144415.xml";
if (File.Exists(path)) Console.WriteLine("Exists");
else Console.WriteLine("Does not exist");

I get Exists every time.
The only difference I can see is the full path - I known my D: drive contains a folder called "Test Data", and that contains a file called "Accounting Voucher Display.pdf 196910351_0_03192019144415.xml".

Check the rest of your path.
If it still looks right, do this:

C#

string[] files = Directory.GetFiles(@"D:\", "*.xml", SearchOption.AllDirectories);

And use the debugger to see exactly what files it can find.
