File inside of a project can be open as:

       File file = new File(path);

or

       File file = new File(./path);

where path is relative path from the project.

For example, when the project name is test and the file with name fileName is inside the test project:

      File file = new File("fileName");

or

      File file = new File("./fileName");

Assuming that you are running your program from F:/test you should use something like:

File f = new File("./test2/doit.txt");

Using hardcoded absolute paths isn't a good idea - your program might not work when user has different directory structure.

Irrespective of which operating system, a file for example, demo.txt can be accessed like

File file = new File("/d:/user/demo.txt");

in Windows where the file is at D:\user\ and 

File file = new File("/usr/demo.txt");

in *nix or *nuxwhere the file is at /usr/

Also, a file if wanted to be accessed relatively can be done as (considering the Windows example) :

Suppose I am in the songs directory in D: like:

D:/
|
|---songs/
|   |
|   |---Main.java
|
|---user/
    |
    |---demo.txt

and the code is inside Main.java, then the following code works.

File file = new File("../user/demo.txt");
