Do what I do - copy it forward every couple years onto new media. My oldest files are from 1977 - proof: https://github.com/DigitalMars/Empire-for-PDP-10 My files have gone from magtape to 8" floppy to various 5.25" floppy to 3.5 floppy to zip drives to cdroms to dvdroms, then to hard disks of ever-increasing size. (My old hard drives are completely unreadable now.) I'm sorry I never kept my punch card decks. I'm sure there was nothing but crap on them, but it would be fun to see what kind of crap it was.

> prevent bit-rot What I do is regularly copy my files forward onto newer media. I started this back in the 1970s, and it is the only reason I still have a copy of the FORTRAN-10 source code of Empire: https://github.com/DigitalMars/Empire-for-PDP-10 All the other stuff I wrote at the time is lost because I stored it on a magtape, and the Caltech magtape drive had drifted so far out of spec the tapes could only be read on that machine which was lost. I managed to preserve that by copying it over a serial line to a PDP-11 and storing it on a PDP-11 floppy. I later was able to save my 11 code by copying it over a much later serial line to an IBM PC, to put on 5.25 disks. As time went by, the files migrated to zip drives, then CD-ROMs, then a long sequence of hard drives (my older hard drives can't be read with modern IDE interfaces, even if

the connector fits, I have no idea why). I remember reading boxes of 5.25 floppies and burning them onto CD-ROMs, a long and tedious process. But now, nothing will read 5.25 floppies any more, but copying a year old hard drive to a new one is a simple process, especially since the new drives are usually much larger than the older ones. Hence I have most of the stuff I worked on since the early 1980s. The old Zortech bulletin board stuff is gone, though, even though I still have the hard drive for it. Nothing can read that old drive. Not that there's anything particularly interesting on it, but I enjoyed running the BBS for many years.
