如何批量重命名以 % 为分隔符的 Windows 文件？

Question

我有很多 Windows 文件，其中文件名包含 %。见下文：

c:\temp>
dir /b

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

我想要做的是从此重命名文件：

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。

Answer 1

如果您使用的是Windows 10，您应该学习和使用 Powershell进行管理和自动化。它非常强大，而且非常有趣。

使用您的示例名称和所需的结果，我选择在 ' %5C '上拆分并使用 -1 的索引，这将获取数组中的最后一个元素，而不管长度如何。

详细：

$path = 'c:\temp'
Get-ChildItem $path | Rename-Item -NewName { ($_ -split '%5C')[-1] }

在控制台：

gci c:\temp | ren -NewName { ($_ -split '%5C')[-1] }

获取子项

Answer 2

我会编写一个 PowerShell 脚本来遍历文件名并使用以下内容重写它们：

$dir = Get-ChildItem -Path "PUTFULLPATHHERETODIRECTORY"
foreach($P in $dir) {
    Rename-Item -path $P -newname $P.FullName.Substring($P.FullName.lastindexof("%5C")+3)
}

首先，我们获取目标文件夹的内容。然后，对于目录中的每个项目，将其重命名为从“%5C”模式的最后一个索引开始的名称，并添加 3 个空格以将其删除。

当然，把完整路径放在我放PUTFULLPATHHERETODIRECTORY 的地方。
