I need to rename bulk files in windows by adding some text in present files name and retaining other part as it is.

Passanger_last_ordercut_X
Passanger_last_ordercut_Y
Passanger_last_ordercut_Z
Passanger_Middle_ordercut_X
Passanger_Middle_ordercut_Y
Passanger_Middle_ordercut_Z

should be renamed to

Passanger_last_ordercut_X_AC
Passanger_last_ordercut_Y_AC
Passanger_last_ordercut_Z_AC
Passanger_Middle_ordercut_X_AC
Passanger_Middle_ordercut_Y_AC
Passanger_Middle_ordercut_Z_AC

I need matlab to import name of files present in given path, rename accordingly and save those files with new name. As in Passanger_last_ordercut_X.cur becomes Passanger_last_ordercut_X_AC.cur

Answer 1

[Walter Roberson]

dinfo = [dir('*_X.cur'); dir('*_Y.cur'); dir('*_Z.cur')];
for K = 1 : length(dinfo)
   oldname = dinfo(K).name;
   [folder, basename, ext] = fileparts(oldname);
   newname = fullfile(folder, [basename '_AC' ext]);
   movefile(oldname, newname);
end

clc; clear all ;
str1 = 'Passanger_last_ordercut_X Passanger_last_ordercut_Y Passanger_last_ordercut_Z Passanger_Middle_ordercut_X Passanger_Middle_ordercut_Y Passanger_Middle_ordercut_Z' ;

rep0 = [{'_X'} {'_Y'} {'_Z'}] ;   % replace these characters
rep1 = [{'_X_AC'} {'_Y_AC'} {'_Z_AC'}] ;   % with these 

for i = 1:length(rep0) 
    str1 = strrep(str1, rep0{i}, rep1{i}) ;
end

thanks a lot for answering but what I need is renaming all files at a particular location.

I cant write 'str1 = 'Passanger_last_ordercut_X Passanger_last_ordercut_Y Passanger_last_ordercut_Z Passanger_Middle_ordercut_X Passanger_Middle_ordercut_Y Passanger_Middle_ordercut_Z' ;

for 100s of files. I need matlab to import name of files present in given path, rename accordingly and save those files with new name. As in Passanger_last_ordercut_X.cur becomes Passanger_last_ordercut_X_AC.cur

How you have got the name of this file so far? That is not a big deal.

% Get all text files in the current folder
files = dir('*.txt');   % txt files 
% Loop through each
for id = 1:length(files)
    % Get the file name (minus the extension)
    fname = files(id).name ;
    %%Rename the file here as discussed above 
    % fnamenew be new file name 
    movefile(files(id).name, fnamenew);

end

I have got these from an output of simulation. These are needed to be uploaded in central server so has to be in .cur format. I am trying your code as well as the one given by Walter Roberson. Thanks.

Aditya, since you asked, you must not know about the FAQ. Both answers are essentially in the FAQ, with the addition of a movefile() in the middle of the loop to do the renaming. Here is the FAQ (there's other good stuff in there too so you should look at it all): http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

Image, thanks a lot for informing me about it. I had never checked it out.
