Thank you, Triple-J.
Yeah, you are right about the dates, I believe. I didn't connect that in my mind before.
Here's my revised decipher:
FrenchAce02
Georges Marie Ludovic Jules --> Forenames
Guynemer --> Surname
23 --> Day of enlistment
11 --> Month of enlistment
1914 --> Year of enlistment
11 --> Day of death
09 --> Month of death
1917 --> Year of death
GuynemerKill.txt --> Link to file of confirmed kills
xxCraft.txt
53
NULL
NULL
NULL
NULL
Capitaine --> Rank
Guynemer.bmp --> Link to photo
Guynemer.txt --> Link to biography
EOR
I guess now the mystery is the "53" and the "EOR". (I've seen that EOR repeatedly throughout the files, so it's probably something really obvious that I'll feel stupid for not knowing!)
