Well, here’s a thing I didn’t know about before that might be useful to you – a tool to extract the dated from the *.crd files.

Man, this might even motivate me to stop putting it off and just jump on the train.

My dad insisted on using CARDFILE.EXE from Windows 3.1 up until he switched to a MacBook in 2010 or so. I still have the data file somewhere.

Gotta admit tho, it was one of the most useful applications that came with a PC back in the late 80s/early 90s. My folks put everything into that thing. They probably had about 350 cards!
