函数说明：
设置成零件放置，默认文件夹中给出的数据库该文件夹的标签。您必须已经指定一个文件夹的数据库标签存在。如果指定的标签，此功能无法创建文件夹不存在的文件夹。

函数参数：
第1个参数为输入：
folder代表参数变量，UF_UGMGR_tag_t 为输入参数类型，该文件夹中的数据库标签。

UF_UGMGR_set_default_folder函数实例代码演示：
这UG/ Open API的程序演示如何进行编码和解码UG/经理的部分文件名。它编码UG /经理部分文件名，并使用该结果来创建新的部分。部分加到名为“测试设置默认文件夹”，如果你的“家”文件夹中的文件夹它的存在。如果“测试设置默认文件夹”不存在，新的部分是添加到您的“家”文件夹中。的名称和新的说明部分在IMAN设置。然后，程序进到询问当前的工作部分（即，该新创建的一部分），和解码UG/经理的部分文件名回到显示有关工作的一部分信息。
