Windows API: Loop through all files on drive with unicode support 2006-11-21 -- Menno De Ruiter I thought I post a post which loops / enumerates all files and dirs on the hd, I had the problem first of the 260 path limitation, but the unicode api's can handle path > 32k length, The routine does not include parse situations, but is okay for general use etc. It also converts the file time into your local time thus UTC + bias SystemTimeToTzSpecificLocalTime etc. TheRoutine routine data TIME_ZONE_INFORMATION Group,pre() TZI:Bias Long TZI:StandardName String(32) TZI:STYear USHORT TZI:STMonth USHORT TZI:STDayOfWeek USHORT TZI:STDay USHORT TZI:STHour USHORT TZI:STMinute USHORT TZI:STSecond USHORT TZI:STMilliseconds USHORT TZI:StandardBias Long TZI:DaylightName String(32) TZI:DDYear USHORT TZI:DDMonth USHORT TZI:DDDayOfWeek USHORT TZI:DDDay USHORT TZI:DDHour USHORT TZI:DDMinute USHORT TZI:DDSecond USHORT TZI:DDMilliseconds USHORT TZI:DaylightBias LONG TZI:Extra String(1024) End FileTime Group,pre() LowDateTime ULong HighDateTime ULong End IFileTime Group,pre() ILowDateTime ULong IHighDateTime ULong End ReturnVal Long GSYSTEMTIME GROUP,PRE() GST:wYear USHORT GST:wMonth USHORT GST:wDayOfWeek USHORT GST:wDay USHORT GST:wHour USHORT GST:wMinute USHORT GST:wSecond USHORT GST:wMilliseconds USHORT END OGSYSTEMTIME GROUP,PRE() OGST:wYear USHORT OGST:wMonth USHORT OGST:wDayOfWeek USHORT OGST:wDay USHORT OGST:wHour USHORT OGST:wMinute USHORT OGST:wSecond USHORT OGST:wMilliseconds USHORT END WIFindData Group,pre() WIFD:FileAttrib Ulong WIFD:CreateTimeLow ulong WIFD:CreateTimeHigh ulong WIFD:LastAccessTimeLow ulong WIFD:LastAccessTimeHigh ulong WIFD:LastWriteTimeLow ulong WIFD:LastWriteTimeHigh ulong WIFD:FileSizeHigh ULong WIFD:FileSizeLow ULong WIFD:Reserved0 ULong WIFD:Reserved1 ULong WIFD:FileName String(65536) WIFD:AlternateFileName String(14) End WOFindData Group,pre() WOFD:FileAttrib Ulong WOFD:CreateTimeLow ulong WOFD:CreateTimeHigh ulong WOFD:LastAccessTimeLow ulong WOFD:LastAccessTimeHigh ulong WOFD:LastWriteTimeLow ulong WOFD:LastWriteTimeHigh ulong WOFD:FileSizeHigh ULong WOFD:FileSizeLow ULong WOFD:Reserved0 ULong WOFD:Reserved1 ULong WOFD:FileName String(65536) WOFD:AlternateFileName String(14) End WWLocalFile String(65536) AIFindData Group,pre() AIFD:FileAttrib Ulong AIFD:CreateTimeLow ulong AIFD:CreateTimeHigh ulong AIFD:LastAccessTimeLow ulong AIFD:LastAccessTimeHigh ulong AIFD:LastWriteTimeLow ulong AIFD:LastWriteTimeHigh ulong AIFD:FileSizeHigh ULong AIFD:FileSizeLow ULong AIFD:Reserved0 ULong AIFD:Reserved1 ULong AIFD:FileName String(260) AIFD:AlternateFileName String(14) End AOFindData Group,pre() AOFD:FileAttrib Ulong AOFD:CreateTimeLow ulong AOFD:CreateTimeHigh ulong AOFD:LastAccessTimeLow ulong AOFD:LastAccessTimeHigh ulong AOFD:LastWriteTimeLow ulong AOFD:LastWriteTimeHigh ulong AOFD:FileSizeHigh ULong AOFD:FileSizeLow ULong AOFD:Reserved0 ULong AOFD:Reserved1 ULong AOFD:FileName String(260) AOFD:AlternateFileName String(14) End ALocalFile String(260) ERROR_FILE_NOT_FOUND Equate(2) ERROR_ACCESS_DENIED Equate(5) TIME_ZONE_ID_INVALID Equate(0FFFFFFFFh) TIME_ZONE_ID_UNKNOWN Equate(0h) TIME_ZONE_ID_STANDARD Equate(1h) TIME_ZONE_ID_DAYLIGHT Equate(2h) !GetTimeZoneInformation(long),long,raw,pascal ZoneInformation long ERROR_NO_MORE_FILES equate(18) LocalFileHandleNew long CurrentQTDirsToDoPosition ULong CurrentQTDirsPosition Ulong code ZoneInformation = GetTimeZoneInformation(Address(TIME_ZONE_INFORMATION)) !!
