【解决方案1】：

Dim obj : Set obj = CreateObject("Scripting.FileSystemObject")
Dim outFile : Set outFile = obj.CreateTextFile("listfile.txt")
Dim inFile: Set inFile = obj.OpenTextFile("listfile.txt")

' read file
data = inFile.ReadAll
inFile.Close

' write file
outFile.write (data)
outFile.Close

此脚本将从大文件中读取行并写入新的小文件。会将第一行的表头（Header）复制到所有子文件中

Dim strLine
lCounter = 1
fCounter = 1
cPosition = 1
MaxLine = 1000
splitAt = MaxLine
Dim fHeader
sFile = "inputFile.txt"
dFile = LEFT(sFile, (LEN(sFile)-4))& "_0" & fCounter & ".txt"
Set objFileToRead = CreateObject("Scripting.FileSystemObject").OpenTextFile(sFile,1)
Set objFileToWrite = CreateObject("Scripting.FileSystemObject").OpenTextFile(dFile,2,true)
do while not objFileToRead.AtEndOfStream
        strLine = objFileToRead.ReadLine()
        objFileToWrite.WriteLine(strLine)
        If cPosition = 1 Then
            fHeader = strLine
        End If
        If cPosition = splitAt Then
            fCounter = fCounter + 1
            splitAt = splitAt + MaxLine
            objFileToWrite.Close
            Set objFileToWrite = Nothing
            If fCounter < 10 Then
                dFile=LEFT(dFile, (LEN(dFile)-5))& fCounter & ".txt"
                Set objFileToWrite = CreateObject("Scripting.FileSystemObject").OpenTextFile(dFile,2,true)
                objFileToWrite.WriteLine(fHeader)
            ElseIf fCounter <100 Or fCounter = 100 Then
                dFile=LEFT(dFile, (LEN(dFile)-6))& fCounter & ".txt"
                Set objFileToWrite = CreateObject("Scripting.FileSystemObject").OpenTextFile(dFile,2,true)
                objFileToWrite.WriteLine(fHeader)
            Else
                dFile=LEFT(dFile, (LEN(dFile)-7)) & fCounter & ".txt"
                Set objFileToWrite = CreateObject("Scripting.FileSystemObject").OpenTextFile(dFile,2,true)
                objFileToWrite.WriteLine(fHeader)
            End If
        End If
        lCounter=lCounter + 1
        cPosition=cPosition + 1
Loop
objFileToWrite.Close
Set objFileToWrite = Nothing
objFileToRead.Close
Set objFileToRead = Nothing

没有解决问题。

【解决方案3】：

写

Set objFileToWrite = CreateObject("Scripting.FileSystemObject").OpenTextFile("C:\listfile.txt",2,true)
objFileToWrite.WriteLine(data)
objFileToWrite.Close
Set objFileToWrite = Nothing

OpenTextFile 参数：

<filename>, IOMode (1=Read,2=write,8=Append), Create (true,false), Format (-2=System Default,-1=Unicode,0=ASCII)

读取整个文件

Set objFileToRead = CreateObject("Scripting.FileSystemObject").OpenTextFile("C:\listfile.txt",1)
strFileText = objFileToRead.ReadAll()
objFileToRead.Close
Set objFileToRead = Nothing

逐行阅读

Set objFileToRead = CreateObject("Scripting.FileSystemObject").OpenTextFile("C:\listfile.txt",1)
Dim strLine
do while not objFileToRead.AtEndOfStream
     strLine = objFileToRead.ReadLine()
     'Do something with the line
loop
objFileToRead.Close
Set objFileToRead = Nothing
