'---------------------- '获得文件夹的大小 'Author = baiyang 'Version = 1.0 'Date = 09.08.08 '---------------------- Option Explicit On Error Resume Next Dim objFSO, objLocalFolder, strArg, longLocalFolderSize, strSizeMess '判断是不是没有路径参数 If WScript.Arguments.Count < 1 Then WScript.Echo "参数无效, 第一个参数为路径" WScript.Quit Else strArg = WScript.Arguments(0) End If Set objFSO = CreateObject("Scripting.FileSystemObject") Set objLocalFolder = objFSO.GetFolder(strArg) If objLocalFolder = Empty Then WScript.Echo "Invalid Path" WScript.Quit End If longLocalFolderSize = objLocalFolder.Size If longLocalFolderSize>=1024 And longLocalFolderSize<1024*1024 Then strSizeMess = Round( longLocalFolderSize/1024, 3 ) & " K" ElseIf longLocalFolderSize>=1024*1024 And longLocalFolderSize<1024*1024*1024 Then strSizeMess = Round( longLocalFolderSize/1024/1024, 3 ) & " M" ElseIf longLocalFolderSize>=1024*1024*1024 Then strSizeMess = Round( longLocalFolderSize/1024/1024/1024, 3 ) & " G" Else strSizeMess = longLocalFolderSize & " B" End If WScript.Echo strSizeMess Set objFSO = Nothing Set objLocalFolder = Nothing WScript.Quit
