Matlab doesn't see a file

I am in the same directory, it collects it in a dir, but exist shows 0 and I can't open it.

Actually, that was just a highlighting issue. I have both files, one with a y, one without, and it only sees the one without. Updated to show this clearly. Note it also see the version with - Copy in it so it's not a length issue.

Also, matlab v2013 was seeing this file right before I upgraded today.

There could be non-printing characters in the name.

dinfo = dir('*.xlsx');
for K = 1 : length(dinfo)
  thisfile = dinfo(K).name;
  disp(thisfile);      %as string
  disp(thisfile + 0);  %as bytes
  r = exist(thisfile);
  if r > 0
    fprintf('File exists, type %d\n', r);
  else
    fprintf('File does not exist??\n');
  end
end

Thats because the file doesn't have a y at the end. Clearly the file shown using dir is

 TEMPOgratingEfficienc.xlsx

and your exist is looking for TEMPOgratingEfficiency.xlsx

[Tom]

Sorry, that was a debug step and I didn't show the actually file. Updated the image to show the issue.

[Joseph Cheng]

I'd say update the picture to show both. I see the file now as it partially cut of under the TEMPOgratingEfficiency - Copy.xlsx. Are you able to put the full path such as

 exist('c:\temporary\thefileimlookingat.xls')

[Kelly Kearney]

In your exist call, you refer to the file as TEMPOgratingEfficiency.xlsx, while the dir list shows TEMPOgratingEfficienc.xlsx. Note the missing y in the latter.

Like the editor recommends, try using the 'file' option in exist(). And like Joseph said, update your screenshot. And attach the "invisible" file so we can check it on our computers.
