Renaming multiple files in a folder
显示 更早的评论
I have files within a folder that have a common filename that I need to omit from all of the files.
For Example:
Antenna_REF_Angle00.s2p
Antenna_REF_Angle45.s2p
Antenna_REF_Angle90.s2p
I want to removed the word "REF" from all of the files in a single loop. Can someone help? Thanks

Try this (untested):
% Removes _REF from all filenames in a folder.
clc; % Clear the command window.
workspace; % Make sure the workspace panel is showing.
format compact;
% Define input and output folders.
% CHANGE THESE FOLDER NAMES!!!!!!
topLevelFolder = pwd;
outputFolder = topLevelFolder;
% Check to see that folder exists.
if ~isfolder(topLevelFolder)
errorMessage = sprintf('Error: The following input folder does not exist:\n%s', topLevelFolder);
uiwait(warndlg(errorMessage));
return;
end
% Get a list of files to copy.
filePattern = fullfile(topLevelFolder, '*.*'); % All files in topLevelFolder ONLY.
% filePattern = fullfile(topLevelFolder, '**/*.*'); % All files in topLevelFolder and subfolders of it.
% filePattern = fullfile(inputFolder, '*.m'); % m-files.
fileNamesToTransfer = dir(filePattern);
numFiles = length(fileNamesToTransfer);
% Do the copying.
for k = 1 : numFiles
% Get the base file name.
baseFileName = fileNamesToTransfer(k).name;
% Skip file if it does not contain "_ref".
if ~contains(baseFileName, '_REF', 'IgnoreCase', true)
continue; % Skip this file.
end
% Replace '_REF' with null.
baseFileName2 = strrep(baseFileName, '_REF', '');
baseFileName2 = strrep(baseFileName2, '_ref', ''); % Do it for lower case also.
inputFolder = fileNamesToTransfer(k).folder;
% Create the full input and output filenames.
fullInputFileName = fullfile(inputFolder, baseFileName);
fullOutputFileName = fullfile(outputFolder, baseFileName2);
fprintf(1, 'Now renaming file #%d of %d: %s to %s\n', ...
k, numFiles, fullInputFileName, fullOutputFileName);
movefile(fullInputFileName, fullOutputFileName);
end
uiwait(msgbox('Done copying files!', 'modal'));

The third argument is the replacement string so if you want _REF to be "REFL" you'd do
baseFileName2 = strrep(baseFileName, '_REF', 'REFL');

It doesn't move it. I know, it's a bad name, but "movefile" is actually the name of the function to rename a file, as well as to move it to a different folder if you want. But if the folder prefixing the filename is the same for both source and destination folder, then the operation will all be in that folder and it's essentially a renaming operation. It doesn't move it anywhere unless the folder prefixed to the front of the full file name is different between the two.
If baseFileName2 was no different than baseFileName, then 'WRxx_THRU' did not occur in baseFileName. If the search string is not there, it just returns the string unaltered.

Folder = 'C:\Your\Folder';
FileList = dir(fullfile(Folder), 'Antenna_REF_*.s2p');
for k = 1:numel(FileList)
oldName = FileList(k).name;
newName = strrep(oldName, 'REF', '');
[status, msg] = movefile(fullfile(folder, oldName), fullfile(folder, newName));
assert(status == 1, msg);
end

dinfo=dir('*.s2p');
for id = 1:length(dinfo)
% Get the file name
[~, f,~] = fileparts(dinfo(id).name);
newname = regexprep(f,'_REF_','');
movefile(dinfo(id).name,[newname '.s2p']);
end

To use this answer, since the code does not use fullfile(), you need to make sure that the current folder is the data folder. So the folder where the files are also must contain the above script (m-file).
