//  The return value is one of the following values:
//  -1: Unable to check. Examine the LastErrorText to determine the reason for failure.
//  0: File does not exist.
//  1: The regular file exists.
//  2: It exists, but it is a directory.
//  3: It exists, but it is a symlink (only possible if followLinks is false)
//  4: It exists, but it is a special filesystem entry type.
//  5: It exists, but it is an unkown filesystem entry type.
//  6: It exists, but it is an socket filesystem entry type.
//  7: It exists, but it is an char device entry type.
//  8: It exists, but it is an block device entry type.
//  9: It exists, but it is an FIFO entry type.
