Hi,
I am trying to rename files in a folder
e.g., rawdata001,rawdata002,rawdata003, etc., upto 100s
with a folder containing the exact same number of files,which i have renamed manually a year ago
e.g., _Batchage, _Oxygen, _CO2, etc.,
I wish to change rawdata001 -> _Batchage,
Also, after renaming, I combine two different sets of files using Matlab, but some of the files are empty, with just headers,
e.g.,
time /tab xyz
h /tab %
is it possible to delete those empty files them using Matlab?
I am noob, hope i explained my question correctly,
Thanks in Advance.

Execute operating system command and return result
Syntax
system('command')
[status, result] = system('command')
[status,result] = system('command','-echo')

I meant you need to execute a system command, like for example to rename a file from myfile1 to myfile to you can do this,
oldpath = 'C:\myfile1'
oldpath = 'C:\myfile2'
[status, w] = dos(sprintf('ren %s %s',oldpath,newpath));
You could copy, say
dos(sprintf('copy %s %s',oldpath,newpath));
or delete, say
dos(sprintf('del %s %s',oldpath,newpath));
instead.

It is not clear what you have tried, or where you are stuck. One part of the solution may be the movefile command to "rename" files, and the delete command to delete files.

This cannot work:
names = ['pO2','oxygen']
The horizontal concatenation of two strings is one string:
names = 'pO2oxygen'
Please post the code you have tried. "It's getting trickier" does not allow to give a suggestion for an improvement.

Please do post your code.
But one small step that might help you is that you can store the separate strings in a cell array:
names = {'pO2','oxygen'.......}
Then, when you need each name, you can access it with
names{1}
which is the contents of the first "cell".
