怎样读取一个文件夹中的所有文件

[huangchao]

我想对某一个文件夹中的文件,包括子目录中的*.txt文件进行处理,打开一个用
Open ("c:\test\001.txt") For Input As #1
Open ("c:\test2\001.txt") For Output As #2

'读入文件内容
Do Until EOF(1)
Line Input #1, temp
s = s & temp
Loop
Print #2, s
Close #2
Close #1
但是不会把说有的文件,包括子目录的读出来循环呀什么的.希望高手指点

利用Dir函数：参考下面的例子

Dim MyFile, MyPath, MyName

' 返回带指定扩展名的文件名。如果超过一个 *.txt 文件存在，
' 函数将返回按条件第一个找到的文件名。
MyFile = Dir("C:\WINDOWS\*.txt")

' 若第二次调用 Dir 函数，但不带任何参数，则函数将返回同一目录下的下一个 *.txt 文件。
MyFile = Dir

' 返回找到的第一个隐式 *.TXT 文件。
MyFile = Dir("*.TXT", vbHidden)

' 显示 C:\ 目录下的名称。
MyPath = "c:\" ' 指定路径。
MyName = Dir(MyPath, vbDirectory) ' 找寻第一项。
Do While MyName <> "" ' 开始循环。
' 跳过当前的目录及上层目录。
If MyName <> "." And MyName <> ".." Then
' 使用位比较来确定 MyName 代表一目录。
If (GetAttr(MyPath & MyName) And vbDirectory) = vbDirectory Then
Debug.Print MyName ' 如果它是一个目录，将其名称显示出来。
End If
End If
MyName = Dir ' 查找下一个目录。
Loop
