Error while reading image in loop to perform some operation on all images in folder

I am getting error, while using this recursive function to read the images and perform some operation on all images in a given folder.

function recursiveFile()
Files=dir('D:\datasets\PRImA_LayoutAnalysisDataset\PRImA Layout Analysis Dataset\Images\*.tif');
for k=1:length(Files)
     Files(k).name;
     image1 = strcat('D:\datasets\PRImA_LayoutAnalysisDataset\PRImA Layout Analysis Dataset\Images\*.tif',Files(k).name);
     i = imread(image1);
     %encode_HTJ2K(image,i,1);
end

function recursiveFile()
Files=dir('D:\datasets\PRImA_LayoutAnalysisDataset\PRImA Layout Analysis Dataset\Images\*.tif');
for k=1:length(Files)
     Files(k).name;
     % You need to change thepath in the below line. Don't use *tif
     image1 = strcat('D:\datasets\PRImA_LayoutAnalysisDataset\PRImA Layout Analysis Dataset\Images\',Files(k).name);
     i = imread(image1);
     %encode_HTJ2K(image,i,1);
end

function recursiveFile()
projectdir = 'D:\datasets\PRImA_LayoutAnalysisDataset\PRImA Layout Analysis Dataset\Images');
Files = dir(fullfile(projectdir, '*.tif'));
for k=1:length(Files)
     image1 = fullfile(Files(k).folder, Files(k).name);
     i = imread(image1);
     %encode_HTJ2K(image,i,1);
end

I deliberately wrote it using the .folder field, because the function name suggests that you might want to search all sub-directories, which you could do by using a small modification,

function recursiveFile()
projectdir = 'D:\datasets\PRImA_LayoutAnalysisDataset\PRImA Layout Analysis Dataset\Images');
Files = dir(fullfile(projectdir, '**', '*.tif'));
for k=1:length(Files)
     image1 = fullfile(Files(k).folder, Files(k).name);
     i = imread(image1);
     %encode_HTJ2K(image,i,1);
end

The '**' tells it to look under all subdirectories recursively.

You can also use:

 image1 = [Files(k).folder,filesep,Files(k).name] ;

instead of

  image1 = strcat('D:\datasets\PRImA_LayoutAnalysisDataset\PRImA Layout Analysis Dataset\Images\',Files(k).name);

function recursiveFile()
% Files=dir('D:\datasets\PRImA_LayoutAnalysisDataset\PRImA Layout Analysis Dataset\Images\*.tif');
folder = "D:\datasets\PRImA_LayoutAnalysisDataset\PRImA Layout Analysis Dataset\Images\";
Files=dir(fullfile(folder, "*.tif");
for k=1:length(Files)
     %Files(k).name;
     image1 = fullfile(folder, Files(k).name);
     i = imread(image1);
     %encode_HTJ2K(image,i,1);
end
