Any realistic tips for handling old digital documents?

I have years of files stored across different platforms. What’s the best way to deal with this without losing important data?

After going through an article on gamehackday.org , I realized that old documents can pose hidden risks. The article explained that legacy files are often forgotten but still accessible, which creates security gaps. It also suggested that reviewing and cleaning up stored data is just as important as protecting new files. What I found insightful was the reminder that digital storage needs regular attention. Reading it helped me understand how proactive file management can prevent future issues.
