'import module' searches directories on sys.path for a file or directory 
named 'module'.  sys.path starts with '.', which represents the 
'current' directory. If you start with the directory containing main.py 
as current directory and 'folder-name' is in the same directory, the 
import should work.  Otherwise ??? EclipseIDE probably modifies the 
current dir and/or path to make things work.

For any more help, post the OS and locations of main.py, folder_name, 
and python.
