I have sorted through my hard disk and threw out about 200MB of old files I really don't need. The rest is properly filed away and ready for backup. The old logs of my websites were - are - more problematic. I don't know if I really have or will have use for them but I don't want to delete them either. I just finished saving a few hundred attachments from my mailbox. They contain the logs of one website. Now my hand, my whole arm up to the shoulder hurts. And I haven't touched the logs of the other - bigger - website yet.
