DiskDigger offers both free and paid versions. The free version has some limitations, but it can still be useful for recovering lost files.

As mentioned earlier, I won't be able to provide an "exclusive free license key" for DiskDigger. The free version has limitations, and if you need more features, you can consider purchasing a license from the official website.
