Bonjour Michel69,

Oui, la fonction FileDateTime,

Dim dt As Date
dt = FileDateTime("C:toto.txt")
MsgBox dt

renvoie la date de dernière modification du fichier.
Si tu as besoin des dates de création, et de dernier accès c'est un peu
plus complexe, via les API. Cela dépends d'une part du système de
fichier NTFS ou FAT32, qui les stocke de manières différentes : UTC
(Coordinate Universal Time) pour NTFS, ou Temps Local (prenant en compte
le fuseau horaire et heure d'été / heure d'hiver) pour FAT32. En plus
simple il y a FSO. Précise ton besoin si nécessaire.


Extrait d'une réponse que j'ai fait sur le forum Windows XP :

C'est conçu comme cela. En NTFS, les dates fichiers sont stockées sur 64
bits en nombre d'intervalles de 100 nanosecondes écoulées depuis le 1
janvier 1601 12:00 en Temps Universel UTC (Coordinated Universal Time).

Ce temps est récupéré par l'api 'GetFileDate', dans une structure FILETIME :

typedef struct _FILETIME {
DWORD dwLowDateTime;
DWORD dwHighDateTime;
} FILETIME, *PFILETIME;

qui est convertie en temps système par l'api 'FileTimeToSystemTime',
dans une structure SYSTEMTIME:

typedef struct _SYSTEMTIME {
WORD wYear;
WORD wMonth;
WORD wDayOfWeek;
WORD wDay;
WORD wHour;
WORD wMinute;
WORD wSecond;
WORD wMilliseconds;
} SYSTEMTIME, *PSYSTEMTIME;

qui est ajusté au temps local par l'api
'SystemTimeToTzSpecificLocalTime' à laquelle on transmet les
caractéristiques régionales dans une structure TIME_ZONE_INFORMATION :

typedef struct _TIME_ZONE_INFORMATION {
LONG Bias;
WCHAR StandardName[ 32 ];
SYSTEMTIME StandardDate;
LONG StandardBias;
WCHAR DaylightName[ 32 ];
SYSTEMTIME DaylightDate;
LONG DaylightBias;
} TIME_ZONE_INFORMATION, *PTIME_ZONE_INFORMATION;

elle même récupérée par l'api 'GetTimeZoneInformation'

Plus de détails ici (en anglais) :

NB : Il y a d'autres moyens d'y parvenir, mais le résultat est le même.
