Too many files open error when using load and save. fclose('all') doesn't solve the problem

My code looks like this
sourcedir = 'C:\exampleDirectory\';
for i = 1:N
exampleFilename = [sourcedir, num2str(i),'.mat'];
structMatrix = load(exampleFilename);
exampleMatrix = structMatrix.savedMatrix;
% do something on exampleMatrix
fclose('all');
end
I have tried sticking an fclose('all') on both ends yet it inevitably runs into:
Error using load
Unable to read file 'exampleFilename'.
Too many files open.
same happens with a similar save function. I tried running it in for loop instead of parfor, the problem persists. I can restart matlab and the problem goes away for a while, only to return when the open file number hits the limit. It is likely happening from load and save functions, but I can't see the code of load and save functions, neither do they output fid for me to close specifically.
Thank you,

I suggest you try https://docs.microsoft.com/en-ca/sysinternals/downloads/process-explorer to monitor which files are being opened. You would then be able to tell whether it is the load() calls.

Try usinng the clear command instead of fclose. This worked in my test here.
clear('structMatrix')

process-explorer that I mentioned would permit you to find out more about what is being opened.
