An alternative, in the unlikely event that isn't good enough:

String fileName="d:\\foldername\\abc.txt";

Note the backslash must be escaped as shown.

You should really use something like
             String separator = System.getProperty("file.separator");

To get the correct character to put in between the bits of the file path and to ensure your code is platform indepndent.

But did you want to know how to define the file path (you app passes the filename in on the command line) or how to parse the file?

Hi,

For windows machine, u need to escape the escape sequence '\' while writing the path.

format:
Drive name:\\\\dir name\\dir name\\file name.extension

e.g. e:\\\\rock\\pritam\\math.txt

For more info refer to this link.
http://java.sun.com/j2se/1.5.0/docs/api/
and check for the class "File".
