    Const sDir1 As String = "file://c|/Temp"
    Const sSubDir1 as String ="Test"
    Const sFile2 as String = "Copied.tmp"
    Const sFile3 as String = "Renamed.tmp"
    Dim sFile As String
        sFile = sDir1 + "/" + sSubDir1
        ChDir( sDir1 )
        If Dir(sSubDir1,16) ="" then ' 目錄是否存在？
            MkDir sSubDir1
            MsgBox sFile,0,"Create directory"
        End If
        sFile = sFile + "/" + sFile2
        FileCopy sFile1 , sFile
        MsgBox fSysURL(CurDir ()),0,"Current directory"
        MsgBox sFile & Chr(13) & FileDateTime( sFile ),0,"Creation time"
        MsgBox  sFile & Chr(13)& FileLen( sFile ),0,"File length"
        MsgBox  sFile & Chr(13)& GetAttr( sFile ),0,"File attributes"
        Name sFile As sDir1 + "/" + sSubDir1 + "/" + sFile3
        ' 在同一目錄中重新命名
        sFile = sDir1 + "/" + sSubDir1 + "/" + sFile3
        SetAttr( sFile, 0 ) ' 刪除所有屬性
        MsgBox sFile & Chr(13) & GetAttr( sFile ),0,"New file attributes"
        Kill sFile
        RmDir sDir1 + "/" + sSubDir1
    End Sub

        iPos = 1
        iPos = Instr(iPos,fSysFp, getPathSeparator())
        Do While iPos > 0
