Hello,
What does your log say, is the libname assigned successfully.
26 libname clean "C:\Users\taran\Documents\SaSUniversityEdition\myfolders ";
NOTE: Library CLEAN does not exist.
Is your log showing this? Then it is clear, that path doesn't exists. Are you trying to read a file in SAS University Editon, then the path you provided is not the right one. You have to use /folders/myfolders/
Check this link for more details: https://support.sas.com/software/products/university-edition/faq/shared_folder_access.htm
Please post your programs and log in the right place.

Thanks,
Suryakiran
