Which obsolete file format is worth to be converted to some nowadays representation ?

Question

Hello,

I believe that there are a lot of old applications that produce some data in their own file formats. As time goes these applications are being substituted. However data format conversion problem remains.

The question is which of popular old-time file formats do you think need to be converted to new ones ?

The motivation of such a question is that I love binary file formats and want to implement file converters and processors. The task would be much more fun if this is something useful.

Thanks in advance, Regards
