Hi There,

Can anyone tell me what is the best way to seperate a filename and a
path so I'm left with 2 strings.

e.g.
Turn this input: "C:\path\to\my\file.txt" into:
String path = "C:\path\to\my";
String file = "file.txt";

as well as turning this: "/path/to/my/file.txt"
String path = "/path/to/my";
String file = "file.txt";

TIA

Intuitively I would use methods in java.lang.String to find the last
instance of the separator character, then create substrings around
that point.

However there are also methods in java.io.File that will do exactly
this for you: getName() and getParent().

String fullPath = new String("/path/to/my/file.txt");
int i = fullPath.lastIndexOf("/");
String path = fullPath.substring(0, i);
String file = fullPath.substring(i + 1);

As was pointed out in an earlier reply, there's another way that IMHO is
most definitely better than anything involving lastIndexOf since the OP
specifically shows x-plat interest. That's the use of the java.io.File
class instead.

Thank you everyone for your speedy reply's. I've based my code on Tim's
reply and it works well...

String fullPath = "/path/to/my/file.txt";
int i = fullPath.lastIndexOf(System.getProperty("file.separator"));
String path = fullPath.substring(0, i);
String file = fullPath.substring(i + 1);

do you mean by using String::lastIndexOf("/");
