90% of the time I open Parts from the recent location, or from a folder by dragging and dropping the file into SolidWorks.  Most of the files open in  30 to 45 seconds.  
On occassion I open a file that may take 3 or more minutes to open.  There are times I don't know that is will take that long and if I did I could have opened the file light weight or in Large design review. 

Would it be nice to get a notification that the file is large and have the option to change the way it opens? 
Would this be a system setting to turn on or off?
