Hi,

According to the API, getParentDirectory(File dir) returns the parent
directory of dir. Does this mean that if I look for a filename "dir", it
will return the name of the directory in which the file is?

Thanks

Huub

why don't you try it and tell us the result?

Have you tried it?

Can you think of any alternative plausible behaviour?

I'm trying to, but I have a conversion question. I'm reading String from
keyboard, which I convert to File:

String tvps = tvpatroon.getText();
FileSystemView fsv;
File file = fsv.createFileObject(tvps);

Then I have to convert it back to String in order to display it with
JOptionPane. Is there a simpler way to do this?

File has all sorts of toString style methods. For a summary of them

I don't think it gets much easier than a single method call:

fsv.getName();
