RE: Getting File Directory Using Any Platform


I don't have multiple platforms to test it on, but I think this will do
it for you:

ToFileName[{$TopDirectory,"Addons","ExtraPackages","Utilities"},
    "Notation.m"]

I want a line of code that will return the directory where the Notation
package is located and it should return a result consistent with the
operating system used.  If the following doesn't work on your platform
please let me know. I am also interested in any improvements to this
code. 


In[1]:= 
  dirs=Which[
    $System==="Microsoft Windows","\\AddOns\\ExtraPackages\\Utilities",
    $System==="Machintosh",":AddOns:ExtraPackages:Utilities",
    True (* Unix *), "/AddOns/ExtraPackages/Utilities"
  ];
  DirectoryName[$TopDirectory<>dirs<>"Notation.m"]


Out[1]=
   C:\Program Files\Wolfram
Research\Mathematica\4.1\AddOns\ExtraPackages\

------------
Thanks,
