When I am trying to delete a file which is present in tomcat server conf/Catalina/localhost from java code then file.delete() always returns false. But if i am checking the file by file.exists() function it returns true.

f.delete() returns false it means that it wasn't / could not be deleted and f.exists() returns true so file exists but cannot be deleted.
