For stand-alone exe, how do I include a folder of files and know how to access them.

I have a folder of files I have added to a stand-alone exe. I have been using Desktop->WindowsStandAloneApplication -> Build. There is a link to add files or directories. I have added a folder which has my data files. However, I don't know how to access them. I have tried

if isdeployed
  mydir = ctfroot ;
  myfile = 'myfile.dat';
  fid=fopen([mydir, myfile]);
else
 ...
end

but it doesn't find the file.

Hi,

everything you add to your project will keep the same folder hierachy. So lets say you have a folder called myfolder and in there a file called myfile.dat. Then you would need to do:

if isdeployed
  fid = fopen(fullfile(ctfroot,'myfolder','myfile.dat'))
end

You can also compile once and not embed the CTF. After compilation, open the ctf file in some zip programm and take a look at the folder structure.

Isn't that what I'm doing?

When you concatenate strings using "[...]" the way you wrote above you are missing the "\" between the file name and path (on Windows at least):

mydir = ctfroot ;
myfile = 'myfile.dat';
[mydir, myfile]

ans =

C:\Program Files\MATLAB\R2012amyfile.dat

This would work better:

mydir = ctfroot ;
myfile = 'myfile.dat';
[mydir,'\',myfile]

ans =

C:\Program Files\MATLAB\R2012a\myfile.dat

But Friedrich's suggestion above to use "fullfile" is a cleaner more robust solution to accomplish the same thing.

sara, we are expecting you to reply to your existing question http://uk.mathworks.com/matlabcentral/answers/218321-cd-statment-and-connection-from-matlab-to-c . You should post your current ctfroot-using code there.
