loading a large trained classifier into the work space

I have trained a linear classifier on a large amount of data using tall arrays, training process takes very long time, about 6 days. i saved the trained classifier using -7.3V file format so that i can use it later as following:

save('gabor_feature_mdl_linear.mat', 'gabor_feature_mdl_linearl', '-v7.3')

the size of the trained classifier is more than 10GB. when i tried to load it to the work space it gives the following error:

"Unable to read file 'F:\gabor_feature_mdl_linear.mat'. Variable name length must be less than or equal to MATLAB maximum name length of 63 characters."

i tried to change the classifier name using a shoter name length, but the error still appears.

i donot want to train the classifer again. any help piease.
