How to Rename and Delete empty files using Mat-LAB?

I am a newbie to Mat-Lab, and I will try to explain my question as clearly as possible, bear with me.

I have two folders "1.Batch" and "2.Batch", both containing, more than 60 files, named "rawdata001.txt","rawdata002.txt","rawda… and so on.. Initially, I renamed everything manually to "pO2.txt", "Oxygen.txt", "Carbondioxide.txt" etc.,

I then retrieved the names from the manually name-changed files containing folder, using dir command, i need to know how can i create a loop so that the names can be changed from rawdata to the specific name,

Then some of these files are empty, they just have headers and units in them but no values, i also would like to know how to remove them using a loop, i tried many things, but its getting trickier,

Can somebody help me?

To rename files. For example

liste_of_files={'rawdat001','rawdata002',...,'rawdata10'}

You want to rename them with

new_name{'carbon','oxygene',...}

for k=1:10
copyfile([yourpath '/' liste_of_file{k}],[yourpath '/' new_name{k}])
end

to delete the empty file by code, I don't think that's a good idea, unless you are experimented.

But is there an option by which i can specify that if the thrid row and column are empty the script can delete files?

fid = fopen('file.txt');
line1 = fgetl(fid);
res=line1;
while ischar(line1)
line1 = fgetl(fid);
res =char(res,line1)
end
fclose(fid);
n=size(res,1)
