Determine if Drive is a local drive

I have a service application that can not use a mapped drive for working directory.
I want to add code to my setup program that will detect if the user has selected a path that is not on a local drive.

How can I detect if a drive is local or if it's a mapped drive?

You need to use the GetDriveType API, which tells you whether a disk drive is a removable, fixed, CD-ROM, RAM disk, or network drive.

UINT GetDriveType(LPCTSTR lpRootPathName);

lpRootPathName: Pointer to a null-terminated string that specifies the root directory of the disk to return information about. A trailing backslash is required. If this parameter is NULL, the function uses the root of the current directory.
Return Values: The return value specifies the type of drive. It can be one of the following values.

DRIVE_UNKNOWN: The drive type cannot be determined.
DRIVE_NO_ROOT_DIR: The root path is invalid. For example, no volume is mounted at the path.
DRIVE_REMOVABLE: The disk can be removed from the drive.
DRIVE_FIXED: The disk cannot be removed from the drive.
DRIVE_REMOTE: The drive is a remote (network) drive.
DRIVE_CDROM: The drive is a CD-ROM drive.
DRIVE_RAMDISK: The drive is a RAM disk.

The API is documented at
