Implementation of reload option for accepting workspaces

The strategy here was not to change much the current code.
For this reason, it does not touch the way it used to deal with the
Loaders.

re #7221
Allow full data path to be given with folders having dots

The issue of the system test was related that the ubuntu and mac os path name
had a folder with a dot. And the input was expecting only a file_name'.'extension.

Now, if it finds more than one dot, it will get only the last one to split
the file - extension.
