Error using load Cannot read file

Hi,

I saved a 6.6 GB mat file with MATLAB 2014b previously and now I need to open it with the same computer and the same version of MATLAB.

I clicked the "open" button under the "HOME" tab in the MATLAB window and found the mat file and "open". However, MATLAB gave me this:

Error using load Cannot read file D:\MATLAB & Simulink Simulation Results\XXX\XXX.mat.

I tried to change the path but it could not work.

Do you know how can I load the large mat file to the workspace?

Thank you in advance!
