As I recall, IGC adopted a file naming system which was used on the
early Cambridge Recorders, which pre-date the specification. But any
flight that is 10 years old or more is history.

The 8-digit filename came about when DOS and Windows where limited to
8-digits. The specification now allows for Long Filenames (see
Specification Appendix 1 Paragraph 2.5.2) but no-one seems to use them.

There's one unexplained item in the GNSS file specification: some loggers,
e.g. the EW model D, have a serial number of the form Dnnnn which does not
convert into the three alphanumeric characters in any obvious way. There's
not a hint in the file specification as to how this feat might be
performed.

The serial number is specified as three alphanumeric characters in both
short and long form file names.
