Using Java and regular expression to fix path

Question

I have a string like this (not always the same filename at the end, this is only example)

\\eabman03\edicom\Aterlasning\repstat.txt

And i want to get this

\\eabman03\edicom\Aterlasning\

So I want to strip the filename at the end of this string with Java. How do I do this most efficient way?

much better than string manipulation, because File abstracts the format of the path. so, for instance, you don't have to worry about whether the 'fileSeperator' is "/" or "\\"

Don't you need a .getAbsolutePath()?

String str = "\\eabman03\\edicom\\Aterlasning\\repstat.txt";
System.out.println(str.substring(0, str.lastIndexOf('\\')+1));

get the lastindex of \
and use String.subString() method

output:

\eabman03\edicom\Aterlasning\

String dirpath = filepath.replaceAll("(?<=\\\\)[^\\]+", "")
