Convert Windows-style path into Unix path [closed]

Answer 1

In general, I never had problems on any operating system with using a '/' as separator.

 new File("/a/b/c.txt");

works at least on Unix, Windows and iSeries.

If you want to be correct, there's a constant 'File.separator', that holds the operating systems separator.

If you want to replace the backslash '\' in a string, remember that it is a special escape character:

String newString = str.replace("\\","/");

edit:

and remember, String is immutable.

 str.replace("\\","/");

will not change the string, only return a new string with the replaced characters.

Answer 2

If all you want to do is be able to access a file with a relative name to a certain directory, you can just use plain File API, like this:

final String baseDir = MainClass.class.getClassLoader().getResource("").getPath();
final String relativeName = "audio/abc.mp3";
final File relativeFile = new File(baseDir, relativeName);
final String canonicalPath = relativeFile.getCanonicalPath();

It should work on both Unix and Windows, since Windows accepts both Unix- and Windows- style paths (just saying it from my own experience).
