I have a few questions about Java's io.file class
You can use the static field File.separator
or, better, use the nio Paths class like this:
File f = Paths.get( "dir1", "dir2", "dir3" ).toFile();
To get something to refer to the absolute path, start the String arguments with a File.separator, which you might get also with nio with this method:
http://docs.oracle.com/javase/7/docs/api/java/nio/file/FileSystem.html#getSeparator%28%29
Under Windows:
File file = new File("C:\\TempFolder\\Images");
File file = new File("C:/TempFolder/Images"); // Because Windows soemtimes is nice.
Under Linux:
File file = new File("/TempFolder/Images");
The reason having two backslashes ( \\\\
), is that in strings a backslash must be escaped: \\t
being a tab character etcetera.
There are no drive letters in Linux, if that was your question. For temporary files you might use File.createTemporaryFile or createTemporaryDirectory.
Directories on other computers may also be used without drive letters, but with UNC paths:
Windows :
\\Server\Directory\Directory
"\\\\Server\\Directory\\Directory"
Linux :
//Server/Directory/Directory
