Feature request for SFV Ninja: add an option to persist checksum results to a specified output file at fixed intervals (e.g., XX mins), so that not all progress is lost upon a system crash.
In my use case, I'm running checksums against large amounts of data that take multiple hours to complete, so a system crash part way through is quite annoying. For me personally, persisting only the completed checksums is perfectly fine: i.e., have the user be responsible for reconciliation/adding back incomplete files.
