I have a program in which I copy file from different location and paste it in a folder but some files have the same name so I want to change the name of that file to the folder of that from where I have copied.

I have almost developed the logic

Path='C:\Users\Anushi Maheshwari\Documents\Intern\shweta_traces\Benign';
cd (Path);
mkdir 'Traces';
rmdir('Traces','s');
folders=ls;
folders(1,:)=[];
folders(1,:)=[];
mkdir 'Traces';
for ii=1:length(folders)
  str=folders(ii,:);
  str=strcat(Path,'\',str);
  cd (str);
  traces=ls('*.txt*');
  copyfile ('*.txt*',strcat((Path,'\Traces\',folders(ii,:),'\.txt'));
end

This code copies the file make a new folder in Traces folder and paste it there but what I want is to change the name of the file according to the subfolder and then paste it in Traces folder.

Any help is appreciated :-)

Are you trying to copy whole folders of files for multiple folders, instead of one file at a time for a single folder?

hmm... ok so I'd recommend using 'dir' which returns a structure (see matlab help) ... also, look at the function 'fullfile' which takes foldernames as strings and handles all the path separators... I've broken up the strings into different lines for clarity...

try this:

Path='C:\Users\Anushi Maheshwari\Documents\Intern\shweta_traces\Benign';
cd (Path);
a = dir();
a(1:2) = []; % remove '.' and '..'
folderNames = a([a.isdir]==1).name;
destFolderName = 'Traces';
mkdir(destFolderName);
for ii=1:length(folders)
  b = dir(fullfile(folderNames{ii},'*.txt'));
  textFileName = b.name;  
  newTextFileName = [folderNames{ii} '_' textFileName]  ;
  fromString = fullfile(folderNames{ii},newTextFileName);    
  copyfile (fromString,'Traces');
end

The code is tried and run as follows.

clear;clc;
Path='path name';
cd (Path);
a = dir();
a(1:2) = []; % remove '.' and '..'
folderNames = a([a.isdir]);
destFolderName = 'new folder name';
mkdir(destFolderName);
for ii=1:length(folderNames)
  b = dir(fullfile(folderNames(ii).name,'*.bmp'));
  for j=1:length(b)
      textFileName = b(j).name;  
      newTextFileName = [folderNames(ii).name '_' textFileName]  ;
      fromString = fullfile(folderNames(ii).name,textFileName);    
      copyfile (fromString,newTextFileName);
      movefile(newTextFileName,destFolderName);
  end
end
