asp中尤其是需要生产静态的cms系统中，经常需要对一些文件进行判断与创建，删除的操作，这里整理了一些，基本上满足了基本需要。

代码如下:
''=====================================
''获得文件后缀
''=====================================
Function Get_Filetxt(ByVal t0)
Dim t1
IF Len(t0)<2 Or Instr(t0,".")=0 Then Get_Filetxt=False:Exit Function
t1=Split(t0,".")
Get_Filetxt=Lcase(t1(Ubound(t1)))
End Function

''=====================================
''读取任何文件的纯代码
''=====================================
Function LoadFile(ByVal t0)
IF Len(t0)=0 Then Exit Function
IF Sdcms_Cache Then
IF Check_Cache("LoadFile_"&t0) Then
Create_Cache "LoadFile_"&t0,LoadFile_Cache(t0)
End IF
LoadFile=Load_Cache("LoadFile_"&t0)
Else
LoadFile=LoadFile_Cache(t0)
End IF
End Function

Function LoadFile_Cache(ByVal t0)
Dim t1,stm
On Error Resume Next
IF Len(t0)=0 Then Exit Function
t1=Empty
Set Stm=Server.CreateObject("Adodb.Stream")
With Stm
.Type=2''以本模式读取
.mode=3
.charset=CharSet
.Open
.loadfromfile Server.MapPath(t0)
t1=.readtext
.Close
End With
Set Stm=Nothing
IF Err Then
LoadFile_Cache="“"&t0&"”"&Err.Description:Err.Clear
Else
LoadFile_Cache=t1
End IF
End Function

''=====================================
''检查文件是否存在
