MATLAB: Matlab 2014b crashing suddently when using a specific folder

crasherrorfolderjavaMATLAB

I've copied a folder of some code from one computer to another. And when I try to access it I get the following matlab error:
Exception in thread "FileDecorationCache request queue" java.lang.OutOfMemoryError: Java heap space

Following that matlab freezes. Why is that happening, what should I do? As long as I dont try to load anything, or even browse in that folder, matlab works fine. I'm using a win 7 – 64 bit machine, Matlab 2014b.

Go into Preferences to the General section and increase Java Heap Memory there. Then restart MATLAB.
