Hi, I need to make a new sub folder within a main folder. When using mkdir(newfolder, newsubfolder) where newfolder is the parent folder where I want the newsubfolder saved, I get syntax errors every time. The full code is attached below.
> In CSVtoMatLab (line 77) Error using mkdir The filename, directory name, or volume label syntax is incorrect.
Error in CSVtoMatLab (line 85) mkdir(newfolder,newsubfolder);
Thanks for any help.
if true
clear all
close all

Have you put breakpoints in?
This kind of thing is usually far quicker to find the problem with by just putting in a breakpoint, looking on the command line at the components you are using and passing to mkdir and seeing the problem than waiting for answers on a forum.
The
mkdir(newfolder, newsubfolder)
syntax works fine in a general case if the arguments you give it are sensible - i.e. an existing parent folder and a valid string for the subfolder.
Obviously you will need to have write access in the folder too though.

Just use one argument:
mkdir(newsubfolder);
And in the for fileidx = 1 : length(fileinfo) loop, get rid of the lines
newsubfolder = fullfile(newdir, subfolderi);
mkdir(newsubfolder)
This has to be done just once for each subfolder, not once for each file in a subfolder.

Yea, that works a little. It creates the two folders within the specified directory. So within the folder 'Test' I get two files, 'Bla' and 'CSV Data'. And within the CSV Data is the data I am saving. Now what I need to happen is the 'CSV Data' folder to be inside of the 'Bla' folder. But this creates both folders inside of the directory, which is not what I want.
I assume I could somehow edit the second directory to point into the 'Bla' folder, so the 'CSV Data' folder is saved within it? I am not sure how to go about that without making it user friendly in the sense that you don't need to edit the directory within the code.
Thanks for the help.
