Hi Jordan, just my thoughts:

Why do you use checksum? For large files, this could take very long. How about mtime or some other timestamp of the filesystem? Is it possible to exclude some files from undo saving? > Things to note: > 3. The undo files are saved in a binary format.

If the undo file is shared between systems that use different binary representation, things will probably go havoc. Without having looked into it, I guess the undo parts contain text that has been undone plus some extra information such as location and time, all of which could be represented in a text format.
