In SAS Viya 4 I want to check if a folder exists

acordes — Fri, 04 Jul 2025 09:57:05 GMT

My starting point is the following:

The data _null_ works as expected, but the filename line gives an error, if the folder does not exist.

How can I wrap it in an %if %then statement? How can I check for the existence of the folder?

filename myfolder FILESRVC FOLDERPATH= "/Reporting/DEV/REG/ABCD/out_json_backup";

data _null_;
  dir_id=exist("myfolder");
  if dnum(dir_id)=0 then do;
       /* do what is necessary if folder is empty */
%put 'hello';
    end;
  rc=dclose(dir_id);
run;

Please check the docs!

exist can be used with datasets and views only
before using dnum and dclose you need to use dopen
