Hello all,
I am reading .hdf files from a folder, matlab reads some of the files and for the remaining files, it gives an error:
file xxx.hdf does not exist.
While i have re-checked the folder all files are there...
Thanks

Please show your code.
Please also show the output of dir() applied to the file, and show the output of fileattrib() applied to the file.

JB, try this:
folder = pwd; % Whatever
fullFilename = fullfile(folder, 'Stringname.txt')
if exist(fullFilename, 'file') == -1
% First filename does not exist.
% Try the other filename.
fullFilename2 = fullfile(folder, 'Stringname2.txt')
if exist(fullFilename2, 'file') == -1
% Neither file exists.
errorMessage = sprintf('Neither filename exists:\n%s\nor\n%s', fullFilename, fullFilename2);
uiwait(warndlg(warningMessage));
else
% The second filename exists.
fullFilename = fullFilename2;
end
end

[~, name, ~] = fileparts(filename);

I think he says he's looking for two possible filenames: it might be either "xxx.hdf" or "xxx2.hdf". I suggest using dir() to find it.
allFileNames = dir('xxx*.hdf');
If there is only one, then the length of allFileNames will be exactly 1. If both of those files exist, or more, then length(allFileNames) will be 2 or more and then he'll have to decide which of the files to use.
