Comments

This function cannot be used to remove a directory, a volume label, or a read-only file. A program can use Set File Attributes (Function 4301h) to change the attributes of a read-only file so that the file can be deleted.

If the specified file is on a network drive, the function deletes the file only if network grants delete access to the drive or directory.
