Hi All,
How can I check if a .pdf file exists in a folder
I know I can use the Exist command if I know the full filename, but I don't have the file name
Thanks,
EDIT: I will need the output as true or false

any(size(dir([yourFolderName '/*.pdf' ]),1))

It's probably better (in terms of different OS support) to use fullfile instead of constructing the path manually.

You could try doing something like:
dir_struct = dir( fullfile(your_path,'*pdf') );
if numel(dir_struct) == 0
% then there are no files with extension "pdf"
else
% there is a "pdf" file in your directory
% dir_struct(1).name gives the file name of the first "pdf" file listed
end
