#Include <WinAPIEx.au3>
_WinAPI_GetVolumeInformation ( [$sRoot] )

参数

$sRoot [可选参数] The root directory of the volume to be described. If this parameter is empty string, the root
of the current directory is used. A trailing backslash is required. For example, you specify
"\\MyServer\MyShare" as "\\MyServer\MyShare\", or the "C" drive as "C:\".

返回值

Success The array that contains the following information:
[0] - The name of a volume.
[2] - The serial number of a volume.
[1] - The maximum length, in TCHARs, of a file name component that a file system supports.
[3] - The flags associated with the file system ($FILE_*).
[4] - The name of the file system, for example, "FAT", "NTFS", etc.
失败: 返回 0 并设置 @error 标志为非 0 值.

注意/说明

When a user attempts to get information about a floppy drive that does not have a floppy disk, or a CD-ROM
drive that does not have a compact disc, the system displays a message box for the user to insert a floppy disk
or a compact disc, respectively. To prevent the system from displaying this message box, call the
_WinAPI_SetErrorMode() function with $SEM_FAILCRITICALERRORS.
