Hi:
It looks like you are accessing the class from the Asia Pacific Region based on your screen shot. Is your class also being taught from that region. If your course conforms to the regular naming convention for OnDemand servers folders, your LIBNAME to that course folder should be something like this:
libname myclass '/home/<yourUserID>/my_courses/u48707812';
Can you right click on the u48707812 folder and choose Properties? That should show you the correct path to use for that folder.
As an alternative, I was able to look up the class associated with that userID for your instructor and there is an alternate path you can use to see the files in the data subfolder -- when I run this code for your class:
libname myclass '/courses/dS7k70m4MpF505gu72kJ2/data';
proc contents data=myclass._all_ nods;
run;
Then I see the files that your instructor has put in the data folder for the class.
If you continue to get error messages when you try to access the folder, then it may be because your class is on a different Region than your account. The FAQ for the OnDemand server says this:
User accounts are normally configured and authorized only for use in their home regions. If you attempt to login or use resources from another region, then you will encounter an error. In most cases, the error will simply report that your account or password is invalid (within that region). But in some cases, other errors might be observed instead.
You may need to work with your instructor so they can send you the data in a zip file to upload to your account in your region.
Hope this helps,
Cynthia
