Try this:
% you'll need to clear the variable dir (and you might as well clear the
% variable cell too) if this is a script and you still have them in your
% workspace (see more below):
clear dir cell
% store your directory as path_name
path_name = 'path\of\directory\where\the\files\are\';
% - use path_name in call to dir() (no need to cd())
% - don't make a variable called dir (or cell) - that conflicts with the
% built-in function dir() (cell())
% - use '*.continuous' to match files with .continuous extension
d_info = dir(fullfile(path_name,'*.continuous'));
% no need to convert the struct array returned by dir() into a cell
% array and then a string array; just use the struct array directly.
file_names = fullfile({d_info.folder},{d_info.name});
channels = [];
for ii = 1:numel(file_names)
channels(:,ii) = load_open_ephys_data_faster(file_names{ii});
end
