file path issue

I have a file path saved in a text configuration file.  I am not able to create the file.  If I hard code the file path, it works.

I have tried to give the file path as "C:\\myDir\\New.txt" as well as with single backslash "C:\myDir\New.txt".

 

 

 

Code below..

 

var filePath1 ='';

 

//this works

filePath1 = "C:\\myDir\\New.txt";

writeToFile(filePath1, "Hello World");

                

//this does not work

filePath1 = getfilePath1(); //the filepath URL is read from a text file

writeToFile(filePath1, "Hello World");
