due to todays obsession with and more long lasting documentation?

I'm not sure it's longer-lasting. I've got VHS and audio tapes I don't have the equipment to play. I've got two voice recorders - each one requiring proprietary software to extract the audio from. The last time I checked, a few years ago, the software was no longer maintained, and may not run on modern Windows machines.

If I put in the effort, I could probably figure out how the files are stored, and how to decode them, but it's not exactly a casual task.
