xv6-file-system-visualizer's Issues

Visualizer not updating when getting Badindir images

If a system image with a bad indirect address in an inode (e.g., Badindir1 and Badindir2 in the cs537 public folder) is uploaded, the visualizer does not update the structural layout. Instead, it displays the layout of the previous image chosen.
