I name digital files using absolute
name as I do for indexcards. In the picture, I show how to make
time stamp with UNIX command to make time stamp name like " , as
example. Kevinmarsh kindly introduced me there is an application
called "TextExpander" which enable text expand "ymd" to the time
stamp. Using the absolute name of digital file, I can link the file
to an indexcard, like
ref. : PDF 2006.11.02 Thu
18:02
Same as link between indexcard, year,
month, date and week is omitted if it is made in same day : then it
become "ref. : PDF 18:02". To find a digital file on computer,
which referenced in a indexcard, search with
"20061102Thu1802".
I usually link only from digital file to card, and not from card to
digital file. It is enough for me because the card system is center
of information in my system.
