I have a big folder "Music", with N subfolders "Pop", "Rock", etc. Each folder has a couple of .flac songs.

I want to create a table in matlab which encodes all this information: it would have four columns (Genre, Artist, Song, Filename) and one row by song.

How could a create such table without doing it by hand?

You can use the dir function to get a full file list:

list=dir('C:\Your\Path\**\*.flac');

Then you can parse each file name to a table entry. The fileparts function is probably going to be useful here to extract folder names from the dir output.

I did something like this:

filelist = dir('C:\Your\Path\**\*.flac');
filenames = cell(length(filelist),2);
for i = 1:length(filelist)
    filenames(i,1) = {num2str(i)};
    filenames(i,2) = {filelist(i).name};
end
disp(table(filenames))
