扩展VBA脚本：实现带分隔符文件名的多目标文件夹文件迁移与重命名

核心实现逻辑 #

• 解析附件文件名，通过指定分隔符（示例为;）拆分出多个目标投资名称
• 调用现有逻辑获取每个投资名称对应的SharePoint文件夹路径
• 先将原文件保存到临时目录，再为每个目标生成重命名后的文件，复制到对应文件夹；或迁移至第一个目标后，再复制到其余目标并重命名
• 重命名规则：仅保留对应投资名称+原文件后缀

Const SHAREPOINT_ROOT As String = "\\your-sharepoint-site.com\sites\Investments\"
' 文件名中分割投资名称的特殊分隔符
Const INVEST_SEPARATOR As String = ";"

关键细节说明 #

• 分隔符适配：可通过修改INVEST_SEPARATOR常量切换不同分隔符（如|、,等）
• 文件名解析：示例中按下划线分割文件名提取投资名称段，可根据实际文件名格式调整Split的索引
• 迁移/复制策略：代码中第一个目标用MoveFile（迁移），其余用CopyFile（复制），可根据需求统一改为复制
• 错误处理：添加了目标文件夹存在性检查，避免因路径无效导致报错
• 临时文件：使用系统临时目录中转，避免占用邮件附件资源
