MATLAB: How to import a specific file

folderfunctionimport

I know how to import a specific file, but what if matlab has two folders set as pathways to check of which both have same filename and filetype, identical.
example: "example.txt"
and their in both folders, and if you importdata('example.txt');
I assume that will just select one of them depending on whichever it encounters first.
Is there a way to select the file through some function I am unaware of?
Cheers, Shane

Use fullfile() to specify the folder and full file name (path + base file name + extension) of the one you want to import.
fullFileName = fullfile(folder1, 'example.txt');
if exist(fullFileName, 'file')
  csvread(fullFileName);
else
  message = sprintf('Warning: %s does not exist', fullFileName);
  uiwait(warndlg(message));
end
