.mat matrix use in folder

I have saved a fixed matrix with a name in my current working Matlab folder on Mac. Now it appears as 'G.... .mat' there when I click on "open" in that folder; together with all my function m-files in there. it takes the identical 368 bytes as in the Mac finder.
How can I work with that saved .mat file inside the local m-files in this folder ?
I tried the 'load G... .mat' command but that does not work; I have tried to run some of my codes with 'G... .mat' in place of my general A matrix input. Does not work work either.
I then tried to see the contents of this .mat file by cicking on it in the local Matlab finder window: This shows nothing.
I have read and tried out all what is advised here and on the general internet. Nothing works for me. Why, oh why did I try to save and multiply use that 'G... .mat' matrix, rather than typing it in by hand everytime I want to work on it again ? Why, oh why?

368 bytes for a .mat file is probably a .mat that has almost nothing in it.
For testing purposes, try using
whos -file "Fully qualified path to file goes here.mat"

Try
dinfo = dir('*.mat');
filenames = {dinfo.name};
nfiles = length(filenames);
for K = 1 : nfiles
thisfile = filenames{K};
fprintf('File name: |%s|\nCharacter codes: %s\n', thisfile, mat2str(double(thisfile)));
whos('-file', thisfile);
end
and see if anything shows up. If it does, then carefully compare the character codes for the name that looks like Godunov.mat to the expected character codes,
double('Godunov.mat')
Check for entries greater than 126, which can indicate unusual characters.
