Organize electronic archives by year

Electronic documents that I no longer need on a day-to-day basis are moved into an Archive folder on my external hard drive. The structure of this archive folder is as follows (adapted from Esther Weidauer’s approach):

Advantages

This structure creates a small reset each year. This way, there is no need for a structure remains in place for decades.

Old and possibly irrelevant documents stay out of sight.

It becomes easier to identify which documents are outdated and can be thrown away, if needed.

Open questions

When modifying a document significantly, should it move to a different year-folder? Or would it be better to not modify the original, and rather modify a copy?

When receiving a document in 2022 describing details from 2021, does the document belong in 2021 or in 2022?
