Cannot display/open NetCDF files - Please help!

Hello,

Thank you very much for reading the question!

I have trouble reading my 31 nc files using ncdisp and netcdf.open. Here's my script:

folder='C:\xxx\';
liste=dir(folder);

for i=3:length(liste)
    ncfile=liste(i).name;
    % open nc
    ncdisp(ncfile)
    ncid=netcdf.open(ncfile);
end

It was working perfectly yesterday, but today it's not working for both ncdisp and netcdf.open after i switched directory folder to work on another m files. After i switched back to the right folder, the problem started. Here is the error message:

Error using internal.matlab.imagesci.nc/openToRead (line 1272)
Could not open 21413_20100615to20120713_qc.nc for reading. 
% 21413_20100615to20120713_qc.nc is the first file i want to open

Error in internal.matlab.imagesci.nc (line 121)
                    this.openToRead();

Error in ncdisp (line 62)
ncObj   = internal.matlab.imagesci.nc(ncFile);

If i turn off the ncdisp and run the netcdf.open, here is the error message:

Error using netcdf.open (line 52)
Could not open file '21413_20100615to20120713_qc.nc'.

Could someone please help me on this? I know it's not about the data because i redownload the same data and it's still stuck. My best shot will be redownloading the netcdf pack again, but i would really like to know the reason behind this. I am using matlab R2019b.

Thank you so much for your help!

ncfile = fullfile(folder, liste(i).name);

It works! Thank you so much!

But what is happening here, why suddenly the previous script stops working after i changed the directory?

In order for the code to work you would have to have been cd to the folder.
