EEGLAB error: 'array exceeds maximum array size preference' due to high number of channels

using the EEGLAB loadeeg.m ( )function for some of the .eeg files I am using apparently the number of channels exceeds 65000 (which I guess is not reasonable) and so I run into the following error:
Requested 65340x4287563198 (2087275.5GB) array exceeds maximum array size preference. Creation of arrays greater than
this limit may take a long time and cause MATLAB to become unresponsive. See array size limit or preference panel for
more information.
It's clear that matlab gives me this error trying to create such a big matrix. Does anyone know how to check what's in my .eeg file or what's the structure of it? I would like to take a look at the data of the file to figure out what might have gone wrong.

Yes, Walter is right. Someone changed the name of the file I was trying to open and therefore something didn't work out when reading it. Maybe checking the header of the file can help.
