My PC's hard drive is a graveyard of old legacy files of things that don't exist anymore, going back several generations

8. Since I have so many old computers, I try to keep ALL my goodies on external disks.

Now and then, I'll move my picture, document and download directories (which many programs use as defaults) from the internal disk over to an external drive.

The external drive(s) can be sneakernetted to another computer, or just shared via the network, and an old computer can serve them up just fine, especially for old files and directories you don't use that often.

I count three drives on the newest computer, including one terabyte of a 4 TB drive designated for incremental backups of the internal drive.

I got a new system, plugged in a couple of drives with the goodies, and was in business immediately, and the internal drive is pretty clean.

HTH
