这些 % 实际上是 : (%3A) 和 \ (%5C) 的十六进制代码。我无法解释当它们从另一个系统复制时它们是如何得到这种方式的，但这是我必须使用的。为清楚起见，这就是十六进制代码的样子。
114902_T:\Accounting\Payables\APA\Boshart Apr 25\BII_inv_1489879.pdf
我想要做的是从这里重命名文件：
114902_T%3A%5CAccounting%5CPayables%5CAPA%5CBoshart Apr 25%5CBII_inv_1489879.pdf
对此：
BII_inv_1489879.pdf
我尝试按照其他重命名示例使用 % 作为分隔符，但更复杂的是最后一个分隔符（pdf 文件名）并不总是第 7 个标记。
任何帮助将不胜感激。
