Fixing broken links

[rikona]

I reorganize my disks and that breaks links. I just found a way to
list broken links and I have several hundred of them. 3 questions:

1. Is there a GUI tool that would help in finding AND repairing ALL
broken links?

2. Is there a way to find/list only circular links/loops, which have
caused me big problems in the past?

3. Before I move/delete/rename a file/dir, is there a way to tell if
that will break links to that object?

Thanks...
