Copy files from one specific folder to multiple folders

Hi everyone. I want to copy FLAC files from one specific folder to multiple folders. I need help with the copying part. I tried many codes but couldn't achieve the desired results. Any help would be appreciated.

[ndata, text, alldata] = xlsread('E:\Thesis\PA\ASVspoof2019_PA_dev\dev-female-trl-3.xlsx')
inputFullFileName = fullfile('E:\Thesis\PA\ASVspoof2019_PA_dev\flac');
filelist   = dir(inputFullFileName);
name       = {filelist.name};
b=name';
b(:);
outputFolder = fullfile(pwd, 'image_sorted');
if ~exist(outputFolder, 'dir')
    mkdir(outputFolder);
end
a=cell2table(alldata);
alldata1.HOMETOWNS1 = categorical(a.alldata2);
SID4 = (alldata1.HOMETOWNS1 == '78')
SID14=alldata(SID4,:)
%Common files name
fun = @(s)any(strncmp(s,b,numel(s)));
out =unique( SID11(cellfun(fun,SID14)))
%Copying
%copy files based on cell array values that matches with input folder and  copy to another new folder that 
% should be created once the folder flac values are matched with out values.

Hi @Yusra Khan,

To copy FLAC files from a specific folder to multiple folders based on criteria from an Excel file, first ensure that the directory listing filters specifically for FLAC files using “dir(fullfile(inputFullFileName, '*.flac'))”.

Then convert the Excel data into a format that allows easy comparison, such as a table or categorical array. Use a matching logic with functions like “contains” to identify files in the directory that correspond to identifiers or criteria extracted from the Excel file.

Then implement a loop to iterate over these matched files and use “copyfile” to copy each one to the desired output directory.

Below is a sample MATLAB code to achieve the same:

% Read data from Excel file
[ndata, text, alldata] = xlsread('E:\Thesis\PA\ASVspoof2019_PA_dev\dev-female-trl-3.xlsx');

% Define the input directory containing the FLAC files
inputFullFileName = 'E:\Thesis\PA\ASVspoof2019_PA_dev\flac';
filelist = dir(fullfile(inputFullFileName, '*.flac')); % List only FLAC files
name = {filelist.name}'; % Get file names

% Convert alldata to a table
a = cell2table(alldata);
alldata1.HOMETOWNS1 = categorical(a.alldata2);
SID4 = (alldata1.HOMETOWNS1 == '78');
SID14 = alldata(SID4, :);

% Define a function to match filenames
fun = @(s) any(strncmp(s, name, numel(s)));
out = unique(SID14(cellfun(fun, SID14)));

% Define the output folder
outputFolder = fullfile(pwd, 'image_sorted');
if ~exist(outputFolder, 'dir')
    mkdir(outputFolder);
end

% Copy matching files to the output folder
for i = 1:length(out)
    match = out{i};
    % Find files that match
    for j = 1:length(name)
        if contains(name{j}, match)
            sourceFile = fullfile(inputFullFileName, name{j});
            destFile = fullfile(outputFolder, name{j});
            copyfile(sourceFile, destFile); % Copy file to the output folder
        end
    end
end

fprintf('Files have been copied successfully.\n');

Please find attached the documentation of functions used for reference:

I hope this will help in resolving the issue.
