Question

问题：下面的脚本循环遍历4,000多万个文件并检索文件属性信息以确定可以清除的内容。目前的流程已经使用了20 + GB的RAM，只完成了一半。

我一直在创建一个大型批处理文件，将每个子文件夹内容写入新的文本文件。这不实用，因为它耗时，而且这是我将在此过程中运行的几台服务器中的第一台。

问题： - 是否可以根据子文件夹循环创建要写入的新文件？（使用object属性代替文件似乎没有诀窍） - 或者可以将内容写入文件，然后从我的临时内存中清除以前的数据吗？

Set objFSO = CreateObject("Scripting.FileSystemObject")
objStartFolder = "C:\Test"

Set colFiles = objFolder.Files

For Each objFile in colFiles
    On Error Resume Next 
    If Err Then
        MyFile.Write "Error accessing " & objFile & ": " & Err.Description & vbCrLf
        Err.Clear
    Else
        Q="""" 'Wrap quotes around string
        strFilePath = Q & objFile.Path & Q

由于您没有提供完整的脚本，因为您引用了未在您提供的代码中实例化的对象，因此告诉您如何操作有点困难。

是的，您可以将每个文件夹的输出写入新文件以及可用内存。您需要稍微更改脚本的结构。我正在为你做这件事，直到我遇到更多未定义的物品并放弃，所以我只是告诉你该做什么。

你不需要两个潜艇，只有一个潜艇。这是结构的轮廓：

Dim fso, startfolder
Set fso = CreateObject("Scripting.FileSystemObject")

startfolder = "C:\temp"
GetFileInfo startfolder

Sub GetFileInfo(folderpath)
    On Error Resume Next
    Dim file, logpath, logfile, folder
    logpath = "C:\log\" & fso.GetBaseName(folderpath) & ".log" ' C:\log folder must exist; but of course edit path and file name conventions as desired
    Set logfile = fso.OpenTextFile(logpath, 2, True)
    If Err Then EchoAndQuit "Failed to create log " & logpath & ": " & Err.Description

    ' Write the file info in current folder
    For Each file In fso.GetFolder(folderpath).Files
        logfile.WriteLine file.Name ' file/security info
    Next

    'Set x = Nothing (Set objects instantiated in this sub to nothing to release memory)

    ' Now the recursive bit
    For Each folder In fso.GetFolder(folderpath).SubFolders
        GetFileInfo(folder.Path)
    Next

    On Error GoTo 0
End Sub


Sub EchoAndQuit(msg)
    MsgBox msg, 4096 + 16, "Failed"
    WScript.Quit
End Sub

这样做的一个问题是，如果您有多个具有相同名称的文件夹，您将收到拒绝访问错误 - 我将留给您制定一些检查/命名约定以避免这种情况。（您可以通过设置logfile = nothing来解决它，但如果有多个具有相同名称的文件夹，您将覆盖现有的日志文件。这样您可以解决一些问题，一些日志文件检查/命名解决重复名称问题的惯例，然后你可以根据需要销毁对象。）

VBScript - 在循环期间使用文件夹名称创建文本文件
