I have done some more work on my File Image Viewer. Fixed some bugs, and added a lot of functionality. The FAT part should be fairly done, though I know of a few things I need to finish. The LeanFS is also mostly done. The other supported file systems have most of their functionality, but if I don't need that functionality at the moment, I probably won't add it yet.
If you would like to see this utility in action, have a look at the page listed above. I would like to know what you find out.
Thanks, Ben.
