What *precisely* are the symptoms when it doesn't work, and what values other than "." have you tried?
It's difficult to help when you're vague about the problem.

DO NOT INDENT USENET POSTS WITH TAB CHARACTERS!
If you're asking the world of strangers to help, please do try to make it easy to read your code.
Use spaces to indent, up to four per level.

Why not 'String[] content = f.list();'?
Extra asssignments to 'null' are not helpful.

Does 'content[i]' contain what you expect?

This value is not used?

What are your outputs in the scenario that "works" (and what does "works" mean?) and in the scenario that doesn't?
