DeleteVolumeMountPointW function (fileapi.h)
Deletes a drive letter or mounted folder.
Syntax
BOOL DeleteVolumeMountPointW(
[in] LPCWSTR lpszVolumeMountPoint
);
Parameters
[in] lpszVolumeMountPoint
The drive letter or mounted folder to be deleted. A trailing backslash is required, for example, "X:" or "Y:\MountX".
Return value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Remarks
Deleting a mounted folder does not cause the underlying directory to be deleted.
If the lpszVolumeMountPoint parameter is a directory that is not a mounted folder, the function does nothing. The directory is not deleted.
In Windows 8 and Windows Server 2012, this function is supported by the following technologies.
| Technology | Supported |

| Server Message Block (SMB) 3.0 protocol | No |
| SMB 3.0 Transparent Failover (TFO) | No |
| SMB 3.0 with Scale-out File Shares (SO) | No |
| Cluster Shared Volume File System (CsvFS) | No |
| Resilient File System (ReFS) | No |
