Hi,
I would like to know how to count the number of .CSV files in my folder? I have to do this for multiple folders so I would like to choose them.
So far I have something like this...
source_dir = uigetdir([]);
d = dir([source_dir, '\*.csv']);
n=length(d(not([d.isdir])));
but I get an error at the second line. Help!

Do you use Mac OS? I had the same problem but then realised it's because I'm supposed to use '/' instead of '\' because it's not Windows.

... and that is why you use fullfile instead of building your own paths by string concatenation. fullfile will do the right thing regardless of which platform you're on.
