A problem with SolidWorks

Hi everyone! I have an external HDD with some SolidWorks files on it. But when I try to open this files it takes very long time(3-10 minutes). I have the same files on my laptop but here it takes only a few seconds these files to be opened from SolidWorks. When I try to copy/paste some files from or to my external HDD I have no problems with the speed. The problem i only by SolidWorks.I use SolidWorks2012. Can someone tell my why this is so, and how can i fix it. Thank you!
