That's not the whole file path - it's a relative path. It probably goes off the current folder and you don't have an afs folder in the current folder. Just specify the whole path, starting from the drive letter, or make sure that folder tree structure is contained in the current folder, and you should be fine.

the problem is they want an interactive call of the function...so i am using uigetfile to get the path. Now there are two ways: somehow I get the current path the folder is in or I get the path to the file beginning in the folder.

The reason I cant just type in the current path is: I dont and maybe never will know the path where they use my program.

Try this snippet:

% Get the name of the file that the user wants to save.
% Note, if you're saving an image you can use imsave() instead of uiputfile().
startingFolder = userpath
defaultFileName = fullfile(startingFolder, '*.*');
[baseFileName, folder] = uiputfile(defaultFileName, 'Specify a file');
if baseFileName == 0
  % User clicked the Cancel button.
  return;
end
fullFileName = fullfile(folder, baseFileName)
