以下VB代码实现的是提取当前目录下的Table.txt数据，然后创建Format.txt文件，按特定格式提取数据保存到里面。
想要改造为自动扫描当前目录下的.txt文件，然后按扫描到的txt文件名创建_Format.txt后缀，然后按特定格式提取数据保存到里面。
比如：当前目录下有123Table.txt，adadf.txt，iiiiii.txt，运行exe后按特定格式提取数据，然后保存为123123Table_Format.txt，adadf_Format.txt，iiiiii_Format.txt。

感谢回答，刚出门了，晚点回去我试试

您好，我试了编译会报Loop缺少Do,看前面已经是有Do While的了，麻烦帮忙看看是哪里出问题了呢，谢谢！

报错解决了，最后我漏了Next Close #1,验证完全符合需求，非常感谢大佬
        Next
        Close #1
        Filename = Dir()                        '下一个文件名
    Loop
