Feature: Tell no paths were found in recursive call

[munozariasjm]

After no files were found we should add this message:

Exception: No files were found within the provided path.

Hey there! I just cheeked and it is working properly for me. When trying to read a file with no .root or .lhe files in recursive mode or not it shows the message:

"Please check the existense of .root files in the specified directory tests/data_tests/signal or use recursive=True. "

I just correct the grammar error in the message above and change it to:

"Exception: No files were found within the provided path. Please check the existence of .{ext} files in the specified directory {path_to_dir} or use recursive=True."

Please let me know if it is working now in order to close the issue.

Great, it returns None, or raises an Exception?

I was checking. The lack seems to be in the ReadRoot for example, in this case, we get:

AttributeError: 'ReadRoot' object has no attribute 'data'

In the case there was no file found

I think that I know that is happening now, but just to be sure that the problem is completely solve, can you show me the code that you are trying to run.
