Rename TIF files in a folder

Hi. I have 21841 TIF format files (in a folder) with names like: Camera_6_100fps_20240403_0956560001, and so to Camera_6_100fps_20240403_09565621841. I want to rename them to the format Camera60001 so on to Camera621841. I have tried a for loop but did not succeed. Can someone please help me with this.

Thanks.

Can you post the for loop that you tried?

% This code is to rename the file names

% Define the directory containing the TIF files
sourceDir = 'G:\Expt\Camera_6';  % Update this path to your directory

% Get a list of all TIF files in the directory
filePattern = fullfile(sourceDir, '*.tif');
tifFiles = dir(filePattern);

% Loop through each file and rename it
for k = 1:length(tifFiles)
    % Get the current filename
    baseFileName = tifFiles(k).name;
    fullFileName = fullfile(sourceDir, baseFileName);
    
    % Extract the index part from the filename
    
    indexStr = baseFileName(end-7:end-4);  
    
    % Construct the new filename
    newFileName = ['Camera6', indexStr, '.tif'];
    newFullFileName = fullfile(sourceDir, newFileName);
    
    % Rename the file
    movefile(fullFileName, newFullFileName);
    
    % Display the old and new file names
    fprintf('Renamed %s to %s\n', fullFileName, newFullFileName);
end

system('touch Camera_6_100fps_20240403_0956560001.tif'); % create files for testing
system('touch Camera_6_100fps_20240403_09565621841.tif');
files = dir('*.tif');
for iFile = 1:numel(files)
    fn = files(iFile).name;
    idx = find(fn == '_', 1, 'last') + 6; % + 6 to skip the timestamp
    newfn = [strrep(fn(1:8), '_', '') fn((idx+1):end)]; % pull out the parts of the filename we want to keep
    movefile(fn, newfn)
end
newfiles = dir('*.tif');
newfiles(:).name

ans = 'Camera60001.tif'

ans = 'Camera621841.tif'

Thank you.

You are quite welcome.

You haven't provided enough detail on how you're attempting to rename these files, but a simple for loop using movefile should be sufficient. You can modify the dest (destination) variable as needed to get the desired naming convention.

files = dir('Camera_6*.tif');
[~, I] = sort([files.datenum]);
files = files(I);

fileNum = 60001;
for file = files'
    src = fullfile(file.folder,file.name);
    dest = fullfile(file.folder,['Camera',num2str(fileNum),'.tif']);
    
    movefile(src, dest)

    fileNum = fileNum + 1;
end

Slightly different approach using regular expression.

files = dir('*.tif');

exp = 'Camera_\d+_\d+fps_\d+_\d{5}(\d+)\.tif';

for file = files'
    matches = regexp(file.name,exp,'tokens','once');
    dest = ['Camera',matches{1},'.tif'];
    movefile(file.name, dest)
end

Thank you.
