Could someone tell me the difference between the two ?.

I am confused between Setting source path when I add files and setting
source path for the Repository.

When you Add files using Component -> Add Files - and set the source path
like
%%11 and %%24 . What does it mean ?. Am I telling CD where to pick up the
files are where to copy the files on the final image.

When you create a new Repository and set the source path. Am I telling TD
where to get the files ?.

Whats the difference between the two ?.
