Vbscript 删除上次修订之前的文件

在一个文件夹中，我有10000个文件，文件名的结构如下：

File1_0, File1_1, File1_2, File1_3 File2_0, File2_1, File2_2 File3_0, File3_1, File3_2, File3_3 ... File1000_0, File1000_1 File1_3 File2_2 File3_3 .... File1000_1

---

解决问题的一种方法是构建一个字典，将文件的基本名称映射到最高版本号：

Set d = CreateObject("Scripting.Dictionary")
d.CompareMode = vbTextCompare

For Each f In fso.GetFolder(sourcefolder)
    basename = fso.GetBaseName(f.Name)
    a = Split(basename, "_")
    revision = Int(a(UBound(a)))
    prefix   = a(0)
    if d(prefix) < revision Then
        d(prefix) = revision
    End If
Next

Set d=CreateObject（“Scripting.Dictionary”）
d、 CompareMode=vbTextCompare
对于fso.GetFolder（sourcefolder）中的每个f
basename=fso.GetBaseName（f.Name）
a=拆分（基本名称“389;”）
修订版=Int（a（UBound（a）））
前缀=a（0）
如果d（前缀）<修订，则
d（前缀）=修订
如果结束
下一个

然后运行第二个循环以删除basename没有该版本的所有文件：

For Each f In fso.GetFolder(sourcefolder)
    basename = fso.GetBaseName(f.Name)
    a = Split(basename, "_")
    revision = Int(a(UBound(a)))
    prefix   = a(0)
    If d.Exists(prefix) And revision < d(prefix) Then
        f.Delete
    End If
Next

fso.GetFolder（sourcefolder）中每个f的

basename=fso.GetBaseName（f.Name）
a=拆分（基本名称“389;”）
修订版=Int（a（UBound（a）））
前缀=a（0）
如果d.存在（前缀）且版本

请注意，此代码假定分隔前缀和修订的下划线是basename中唯一的下划线。如果文件名包含多个下划线（如

foo\u bar\u 1.txt

），则需要调整前缀和修订的提取以解决此问题

话虽如此，我强烈建议不要在文件名中进行修订管理。使用版本控制系统（Git、Mercurial、Subversion等）。这就是它们被发明的目的。

您已经发布了一些代码，但实际问题是什么？在从数组中删除名称后，我如何用上一个修订版重新生成名称，并删除其余的名称？Ansgar，谢谢您的建议！（但就目前而言，我是最终用户，因此修订控制系统的功能过于强大）。如何，您的代码在我的机器上不工作（可能是我）“代码不工作”不是问题描述。你希望我如何调试它？我不是坐在你的电脑前。另外，不，即使你是唯一的用户，设置RCS也不过分。很抱歉，我想说的是，你的代码运行时没有任何错误，但它没有删除任何内容。我没有调试/编程工具（我不能在这台机器上安装任何东西）来准确地告诉我刚才在notepade-

WScript.Echo

等中使用的问题是什么……但是这一行

d.Exists（basename）和revision

的操作不正确。@white\u标记我的错误。字典的键必须是basename的前缀部分，而不是整个basename。固定的。
