I'm not so certain on how that information you hold can help you recover your dogecoin, but since the only problem is the file which was deleted, maybe you can use a recovery tool to recover your deleted files, I think it's possible, just try to search that tool that could help you, a youtube tutorial might help if you are not so tech savvy.
i would do this if i knew what file i was looking for.
Maybe, you can find some notes to give you some hints(if there are)? But if there is nothing, I'm afraid you could not recover them anymore.
This will serve you a lesson to learn, you need to have some back-up files, a copy from your important documents to anticipate in a case like this. This what I usually do, I save it to USB, keep it that no one knows, and I'm no longer worried even if my PC or laptop will be corrupted.
