Renaming and deleting files using MatLab

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.

How do you determine which new name matches to which rawdataXYZ?

Answer 1

 doc system

system

Execute operating system command and return result

Syntax

 system('command')

 [status, result] = system('command')

 [status,result] = system('command','-echo')

I do not see a connection between this answer and the question.

Me neither, :/

[Babak]

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.

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,

i have a matrix named

names = ['pO2','oxygen'.......] oldnames = ['rawdata001.txt',....60.txt]

i need to rename it from rawdata to pO2,

Then some of these files are empty, they just have headers and units in them but no values, that is, first two lines have names on it, but nothing after that, no values or numbers,

 i also would like to know how to remove them using a loop, i tried many things, delete command, but its getting trickier,

Thanks for the reply

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".
