每天早上7点左右， 3 csv导出被提取到特定文件夹中，文件名每天都完全相同，除非每天将文件名的前缀修改为当前日期。
示例：
16-02-2018_Test1 将更改为 17-02-2018_Test1
16-02-2018_Test2 将更改为 17-02-2018_Test2
16-02-2018_Test3 将更改为 17-02-2018_Test3
不替换文件本身，而是将具有当前日期的新文件添加到此文件夹中。
我需要做的是每天识别3个提取物并将它们复制到子文件夹中。我想到这样做的最好方法是确定上次修改文件的日期。
我找到了下面的VBS代码并帮助识别目录中的最新文件，并添加了一行将该文件复制到新目录。
然而，问题是代码只识别1个文件而不是3个而我只能复制1个文件而不是3个。如果有人有更好的代码来帮助我实现所需的结果或或者可以帮助修改现有代码以实现所需的结果。
sPath = "C:\Users\Desktop\Test\"
Const sToDir = "C:\Users\Desktop\Test\NewFolder\"
Set oFSO = CreateObject("Scripting.FileSystemObject")
sNewestFile = GetNewestFile(sPath)
If sNewestFile <> "" Then
WScript.Echo "Newest file is " & sNewestFile
dFileModDate = oFSO.GetFile(sNewestFile).DateLastModified
If DateDiff("n", dFileModDate, Now) > 60 Then
oFSO.CopyFile sNewestFile, sToDir
End If
Else
WScript.Echo "Directory is empty"
End If
Function GetNewestFile(ByVal sPath)
sNewestFile = Null ' init value
Set oFSO = CreateObject("Scripting.FileSystemObject")
Set oFolder = oFSO.GetFolder(sPath)
Set oFiles = oFolder.Files
' enumerate the files in the folder, finding the newest file
For Each oFile In oFiles
On Error Resume Next
If IsNull(sNewestFile) Then
sNewestFile = oFile.Path
dPrevDate = oFile.DateLastModified
Elseif dPrevDate < oFile.DateLastModified Then
sNewestFile = oFile.Path
dPrevDate = oFile.DateLastModified
End If
On Error Goto 0
Next
If IsNull(sNewestFile) Then sNewestFile = ""
GetNewestFile = sNewestFile
End Function

在一个有用的格式类和
中投入一些工作或
在代码中：
Option Explicit
' stolen from https://stackoverflow.com/a/21643663/603855
' added formatTwo; left as exercise: formatThree
Class cFormat
Private m_oSB
Private Sub Class_Initialize()
Set m_oSB = CreateObject("System.Text.StringBuilder")
End Sub ' Class_Initialize
Public Function formatOne(sFmt, vElm)
m_oSB.AppendFormat sFmt, vElm
formatOne = m_oSB.ToString()
m_oSB.Length = 0
End Function ' formatOne
Public Function formatTwo(sFmt, vElm1, vElm2)
m_oSB.AppendFormat_2 sFmt, vElm1, vElm2
formatTwo = m_oSB.ToString()
m_oSB.Length = 0
End Function ' formatOne
Public Function formatArray(sFmt, aElms)
m_oSB.AppendFormat_4 sFmt, (aElms)
formatArray = m_oSB.ToString()
m_oSB.Length = 0
End Function ' formatArray
End Class ' cFormat
Dim oFmt : Set oFmt = New cFormat
Dim sFmt : sFmt = "{0:dd-MM-yyyy}_Test{1}"
Dim dToday : dToday = Date()
Dim i
WScript.Echo "file names expected today " & oFmt.formatOne("({0:yyyy-MMM-d}).", dToday)
For i = 1 To 3
WScript.Echo oFmt.FormatTwo(sFmt, dToday, i)
Next
WScript.Echo oFmt.formatArray("look for {0} if {1} is missing on the {2:dd}th after 7 AM" _
, Array(oFmt.FormatTwo(sFmt, DateAdd("d", -1, dToday), 1), oFmt.FormatTwo(sFmt, dToday, 1), dToday))
Dim sFnd : sFnd = oFmt.FormatTwo(sFmt, dToday, 2)
WScript.Echo "if your GetNewestFile() finds " & sFnd & ", copy:"
For i = 1 To 3
WScript.Echo Left(sFnd, Len(sFnd) - 1) & i
Next
输出：
cscript 48866113.vbs
file names expected today (2018-Feb-19).
19-02-2018_Test1
19-02-2018_Test2
19-02-2018_Test3
look for 18-02-2018_Test1 if 19-02-2018_Test1 is missing on the 19th after 7 AM
if your GetNewestFile() finds 19-02-2018_Test4, copy:
19-02-2018_Test1
19-02-2018_Test2
19-02-2018_Test3

感谢大家的帮助，我在另一个主题上找到了答案。这是链接：Copy 2 latest text file from a source folder to destination folder
