While what you are doing is not breaking the program, it potentially
can. Instead of copying all of the .vi files in the llb to a
directory, just try to double-click one of the .vi files in the .llb.
This will open up that VI. The issue with copying them all to a
directory (as you are doing) is if you miss one, there may be broken
links if these VIs are linked to eachother (they likely are).
Also, if they are slightly more complicated (i.e. make use of relative
paths), this method will also break the VIs.
