Remarks

To scan a volume

  1. Open a handle to the volume.

    The name of the volume to open has the format \FolderName\Vol:, where FolderName is the name that FATFS uses for the root directory name of the mounted volume.

  2. Call DeviceIoControl with the volume handle and IOCTL_DISK_SCAN_VOLUME.

    This following code example shows this procedure.

    hVolume = CreateFile(TEXT("\Storage Card\Vol:"), 
GENERIC_READ|GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0, NULL); 
DeviceIoControl(hVolume, IOCTL_DISK_SCAN_VOLUME, NULL, 0, NULL, 
0, lpBytesReturned, NULL);

Requirements

OS Versions: Windows CE 2.12 and later.

Header: Diskio.h.
