rename photos in a specific folder

Hello everybody,

I have a set of photos in a specific folder. Let say they start from Image00000_IR1 to Image00100_IR1. What I want is to rename these photos, so they will become Image00101_IR1 to Image00199_IR1. Is there a way that we could do that in MATLAB?

Thanks in advance.

Is it only the 3rd zero that needs to be changed to 1? Like

outputFileName = inputFileName;
outputFileName(8) = '1';
movefile(inputFileName, outputFileName);

or does it need to be more general than that, like add a hundred to whatever number is there?

I think that would not work with a folder that contains a hendred photo.

Should I put it in a loop or something?

Anyhow, I got a code from someone and I did it on my photos and I got an error says "Cannot copy or move a file or directory onto itself."

The code is:

base = 'F:\(second week)\Position1 - Copy';  % Set accordingly
list = dir(fullfile(base, '*.mim'));
for iList = 1:numel(list)
  name = list(iList).name;
  index = strfind(name, '.');  % Example, use "20110331093455.dcm"
  newName = (name(1:index(1)-1)); 
%   newName = ('Image10001_IR1'); 
  movefile(fullfile(base, name), fullfile(base, [newName, '.mim']));
end

I dont know where is my error? Could you help me with that?

"I dont know where is my error?"

The orignal name and the new name are exactly the same. It appears that you might want to change the file extension, but your code just uses exactly the same file extension.

The robust and recommended way to split the filename and file extension is to use fileparts, rather than messing about with indexing like this code does.

Why can't you just essentially follow the way I did it in your almost identical question:

I did the code but there are no files in the folder Renmed!
