I have a lot of files ^(what?) and I like to know how old things are.

It's personally important to me that I keep archives, as I've been making things since I was little and have moved and duplicated stuff from machine to machine over the years.

There's two ways I do this. One is to index earliest files ages found by file name, which is what I do for my notes and articles, as those rarely change file names (and a renamed version is generally renamed for a reason, ie. it's distinct enough to warrant renaming).

For non-text file types or for larger and older archives where there are more cases where the same file has been used in multiple places with different names, I have an open source notebook I use which you can try out for yourself!
