Filenames and pathnames
To access any file or directory, you must specify a pathname, a symbolic name that tells a program where to find a file within the directory hierarchy based at root (/).
A typical BlackBerry PlayBook OS pathname looks like this:
In this example, .profile is found in the fred directory, which in turn resides in the home directory, which is found in /, the root directory:
Like Linux and other UNIX-like operating systems, BlackBerry PlayBook OS pathname components are separated by a forward slash (/). This is unlike Microsoft operating systems, which use a backslash (\).
