Files

I can’t tell you how many times I was told something would go in my permanent file.
I always wondered where they kept those files. And if they bothered to convert all the old records to computer files when hard drives and computers got cheap.
What do they do with those things when people die? Do they burn the paper records and delete the computer files, or do they burn them to a CD or write them to a tape, stacking all the dead records in a box and putting them in a storage room?
Can this be considered immortality?
