Properties file unload

The following problem occurs :

When i load properties - i get from a file - into the system

FileInputStream propFile =new FileInputStream("myProperties.txt");

Properties p =new Properties(System.getProperties());

p.load(propFile);

// set the system properties

System.setProperties(p);

and i want to delete that file later on to create another file with the same name... it doesn't delete that file.

My question is...is there a possibility to first UNLOAD that properties-file,so i can get rid of 'myProperties.txt'

thx
