I have a set of binary files loaded from a old hard drive that I can see using binary-file-viewer program. Yet, the code
[Fid,message] = fopen(fnames.name,'r');
generates Fid=-1 and error message "no such file _ _ _". I can see the filename and other characteristics in matlab command windows! What's strange is that if I point the directory to a different set of binary files, all is well! Please note that the filenames in both cases are about 18 to 21 characters long and suffix is .dat in both cases. Completely stumped!

Are there any funny non-displaying characters in the file names? E.g., what does this show:
d = dir;
d = [d.name];
any(d<' ')
or
dir(fnames.name)
