Does anyone have a Matlab code that would delete part of filenames in many directories?

I have a large number of waveform records that have been saved as individual files in many directories.

The directory structure is \RawData\Cell01, \RawData\Cell02, \RawData\Cell03...\RawData\Cell99

The data files in each of these subdirectories are named Cellxx_00000_xxxxx.xxx except the first file which is Cellxx_00000.dat

For example I have a subdirectory \RawData\Cell01 that may contain several thousand files named Cell01_00000_00001.dat, Cell01_00000_00002.dat; Cell01_00000_00003.dat… Cell01_00000_04300.dat.

I would like to:

remove the characters "_00000" from these files and rename them as: Cell01_00001.dat, Cell01_00002.dat, Cell01_00003.dat ... Cell01_04300.dat, and
copy the renamed files to subdirectory \RawData\Renamed\Cell01. The file Cell01_00000.dat must not be changed.

Does anyone have a code that could perform this task?

I have edited the code to fix the reference to filename

在 MATLAB Online 中打开

Given a filename

newfilename = regexprep(filename, '000000_', '');

The rest is just finding files and copyfile()

The below needs R2016b or later

projectdir = 'RawData';
outdir = fullfile(projectdir, 'Renamed');
if ~exist(outdir, 'dir'); mkdir(outdir); end
dinfo = dir( fullfile(projectdir, 'Cell*', '*.dat') );
fullnames = fullfile( {dinfo.folder}, {dinfo.name} );
for K = 1 : length(fullnames)
    thisfile = fullnames{K};
    [fulldir, basename, ext] = fileparts(thisfile);
    [parentdir, basedir] = fileparts(fulldir);
    newfilename = [regexprep(basename, '000000_', '', 'once'), ext];
    newdir = fullfile(outdir, basedir);
    if ~exist(newdir, 'dir'); mkdir(newdir); end
    newfilename = fullfile(newdir, newfilename);
    copyfile(thisfile, newfilename)
end

Thanks for the code. What does the string 'first" in the regexprep(filename, '000000_', '', 'first'), do? I could not find this under the possible options for regexprep().
