Michal -

Given that you are looking for notes other than in code, they will almost all be instances of Text, of which there are relatively few, otherwise, in the image.  This will be a much better basis for the enumeration than all instances of String.  Let us know if you get exasperated.

It is unfortunate that this happened.  Of course there are many ways that it could have been prevented, but the absoluteness of the failure is out of the ordinary.  I do not think it would be all that hard to allow Squeak to fail from the save primitive, and keep running.  This would at least afford a chance to delete other files from Squeak and try again.  Hopefully we can improve things so that this will not happen again in the future.
