Check and delete windows directory

I would like to check if a windows directory is empty, if so delete it otherwise end.

Is this possible via SAS Base 9.4 and Windows 7

Its possible, and there are a few options. You could stream in a dir pipe (not tested):

filename tmp pipe 'dir "c:\temp" /b';

data _null_;

infile tmp dlm="¬";

input buffer $;

if buffer="your dir" then found=1;

run;

Or you could do it in a macro:

And to delete:

The question is, why. I generally try to avoid doing OS manipulations through SAS, especially through macro, as an unresolved macro, or problem url could lead to all kinds of problems. Most of the time I find there are systematci problems if your having to do this anyways.
