windows nt/access other directories/ attach/system

As recommended, I keep separate directories for projects, but also use
separate sub-directories for types of data (e.g. different oceanographic
instruments) within projects.

My problem is that I often need to access the objects and data (not
stored as objects) in more than one directory.

I understand (mistakenly?) that at present you cannot use attach() with
directories, just with objects and packages. Also I think
system("command") is for the UNIX environment. System("cd ..") gives
me an error under Windows NT.

system() does work under Windows, but system("cd ..") wouldn't change the
working directory even under Unix. setwd() is for changing directories.
