How to detect if directory is writible in JAVA

File f = new File("C://Documents and Settings//All Users//Documents");
    if(f.canWrite())
        System.out.println("The directory is writable");
    else
        System.out.println("The directory is not writable");

isn't it suppose to be backslash .forward slash is for unix systems only

You can use:

File.separator

The system-dependent default name-separator character.
