  • 项目

This structure describes a file found by the FindFirstFile or FindNextFile function.

typedef struct _WIN32_FIND_DATA { 
DWORD dwFileAttributes; 
FILETIME ftCreationTime; 
FILETIME ftLastAccessTime; 
FILETIME ftLastWriteTime;

DWORD nFileSizeLow;

} WIN32_FIND_DATA;

Members

  • dwFileAttributes
    Specifies the file attributes of the file found. It can be one or more of the following values:

    Value Description
    FILE_ATTRIBUTE_ARCHIVE The file or directory is an archive file or directory. Applications use this attribute to mark files for backup or removal.
    FILE_ATTRIBUTE_COMPRESSED The file or directory is compressed. For a file, this means that all of the data in the file is compressed. For a directory, this means that compression is the default for newly created files and subdirectories.
    FILE_ATTRIBUTE_DIRECTORY The handle identifies a directory.
    FILE_ATTRIBUTE_ENCRYPTED The file or directory is encrypted. For a file, this means that all data streams are encrypted. For a directory, this means that encryption is the default for newly created files and subdirectories.
    FILE_ATTRIBUTE_HIDDEN The file or directory is hidden. It is not included in an ordinary directory listing.
    FILE_ATTRIBUTE_INROM This file is an operating system file stored in ROM. These files are read-only; they cannot be modified.
    FILE_ATTRIBUTE_NORMAL The file or directory has no other attributes set. This attribute is valid only if used alone.
    FILE_ATTRIBUTE_READONLY The file or directory is read-only. Applications can read the file but cannot write to it or delete it. In the case of a directory, applications cannot delete it.
    FILE_ATTRIBUTE_REPARSE_POINT The file has an associated reparse point.
    FILE_ATTRIBUTE_ROMMODULE This file is an operating system file stored in ROM and executed directly from ROM, rather than being first copied to RAM. The CreateFile function cannot be used to access this file, instead the LoadLibrary and CreateProcess functions must be used.
    FILE_ATTRIBUTE_ROMSTATICREF The file is a DLL module that has a static reference from at least one other file that is in the modules section of the image. A file having this attribute can not replace the functionality of the DLL with a RAM copy of the same DLL. A file having this attribute must also have the FILE_ATTRIBUTE_INROM and FILE_ATTRIBUTE_ROMMODULE attributes.
    FILE_ATTRIBUTE_SPARSE_FILE The file is a sparse file.
    FILE_ATTRIBUTE_SYSTEM The file or directory is part of the operating system or is used exclusively by the operating system.
    FILE_ATTRIBUTE_TEMPORARY The file is being used for temporary storage. File systems attempt to keep all of the data in memory for quicker access, rather than flushing it back to mass storage. A temporary file should be deleted by the application as soon as it is no longer needed.

  • ftCreationTime
    Specifies a FILETIME structure containing the time the file was created. FindFirstFile and FindNextFile report file times in Coordinated Universal Time (UTC) format. These functions set the FILETIME members to zero if the file system containing the file does not support this time member. You can use the FileTimeToLocalFileTime function to convert from UTC to local time, and then use the FileTimeToSystemTime function to convert the local time to a SYSTEMTIME structure containing individual members for the month, day, year, weekday, hour, minute, second, and millisecond.

  • ftLastAccessTime
    Specifies a FILETIME structure containing the time that the file was last accessed. The time is in UTC format; the FILETIME members are zero if the file system does not support this time member.

  • ftLastWriteTime
    Specifies a FILETIME structure containing the time that the file was last written to. The time is in UTC format; the FILETIME members are zero if the file system does not support this time member.

  • nFileSizeHigh
    Specifies the high-order DWORD value of the file size, in bytes. This value is zero unless the file size is greater than MAXDWORD. The size of the file is equal to (nFileSizeHigh * MAXDWORD) + nFileSizeLow.

  • nFileSizeLow
    Specifies the low-order DWORD value of the file size, in bytes.

  • dwOID
    Specifies the object identifier of the file.

  • cFileName
    Null-terminated string that is the name of the file.

Remarks

If a file has a long file name, the complete name appears in the cFileName member, and the 8.3 format truncated version of the name appears in the cAlternateFileName member. Otherwise, cAlternateFileName is empty. As an alternative, you can use the GetShortPathName function to find the 8.3 format version of a file name.
