matlab online how to reference file in folder at same directory

Hi,

I'm using Matlab online. In my Matlab drive i have a folder in the same directory that my main.m . The folder is callded "Test2" and inside is a csv file, named 'testeXPTO.csv'. My code in main.m is this:

fid=fopen('../Test2/testeXPTO.csv');
C = textscan(fid, '%s','delimiter', '\n');

The error is:

Error using textscan Invalid file identifier. Use fopen to generate a valid file identifier.

What is the code to relative reference a path of a file that is inside a folder in the same directory that my main.m in Matlab online.

Thanks Your Francisco

Please show us both the fid and msg values:

[fid,msg] = fopen('../Test2/testeXPTO.csv')

Now it's working. Sorry but, i swear than earlier today i got the error that i show above. But now even when i use:

fid=fopen('../Test2/testeXPTO.csv');

it's OK. Thanks.
