从文件中获取扩展属性

Question

我试图从脚本运行的文件夹中的视频文件获取扩展文件属性，并将结果输出到文本文件。

这是我到目前为止的代码：

Dim ls, fsObj, fd, fs, fl, sfs, sf, tf 

    ' specify the file extensions to list 
    dim fileTypes 
    fileTypes = Array("mp4","mkv","avi") 

On Error Resume Next 

    ls = "" 
    Set fsObj = CreateObject("Scripting.FileSystemObject") 
    Set fd = fsObj.GetFolder(".") 
Set objFolder = objShell.NameSpace(fsObj) 
    set fs = fd.Files 

For Each fileName in objFolder.Items 
    set objFolderItem = objFolder.ParseName(fileName) 
    size = objFolder.GetDetailsOf(objFolderItem, 1) 
    length = objFolder.GetDetailsOf(objFolderItem, 27) 
    height = objFolder.GetDetailsOf(objFolderItem, 283) 
    width = objFolder.GetDetailsOf(objFolderItem, 285) 
Next 


    ' list subfolders 
    set sfs = fd.SubFolders 
    For Each sf in sfs 
     ls = ls & sf.name & vbCrLf & chr(10) 
    Next 

     For Each fl in fs 
     ' check whether the extension matches 
     if arrayContains(fileTypes, fsObj.GetExtensionName(fl.name))then 
    ls = ls & fl.name & vbtab & length & vbCrLf & chr(10) 

     end if 
    Next 
    Set tf = fsObj.OpenTextFile("index.txt", 2, True, False) 

    tf.Writeline ls 

    tf.Close 
    Set fsObj = Nothing 

    function arrayContains (arr, val)    
     dim found 
     found = false 
     for i = 0 to ubound(arr) 
      if arr(i) = val then  
       found = true 
       exit for 
      end if 
     next 
     arrayContains = found    
    end function 

我试图获取文件名和长度，一旦我能，我可以添加其他。

据我猜测，我需要指定objFolder.ParseName（fileName）。我如何指定与文件类型数组匹配的所有文件？我试过fl.name和fd.files。我不知道还有什么要尝试。

我双击在Windows 7

脚本从Windows资源管理VBS文件运行脚本，没有错误，运行和返回的文件名，但不返回扩展属性。任何帮助将不胜感激。

下面的代码能够获取像mp4文件的名称，大小，长度，帧高度和帧宽的详细信息。对于格式为flv，avi，mkv的文件，只能提取它们的名称和大小。对于这些文件，即使在右键单击它们时，选择属性并转到“详细信息”选项卡，您将看不到有关它们的长度，高度和宽度的信息。但是对于mp4，你会看到所有这些细节。

试试这个代码：

Set fso = CreateObject("scripting.filesystemobject") 
Set obs = CreateObject("shell.application") 
Set fol = fso.GetFolder(".") 
Set spl = obs.NameSpace(fol.Path) 
Set files = fol.Files 
filePath = fol.path&"\Info.txt" 
set objFile = fso.openTextFile(filePath,2,true,true) 

arr = Array("mp4", "mkv", "avi", "flv") 

For Each file In files 
    ext = fso.GetExtensionName(file.Name) 
    For Each ex In arr 
     If StrComp(ext,ex,1)=0 Then 
      objFile.writeline "NAME: "&spl.GetDetailsOf(spl.ParseName(file.Name),0)&vbcrlf&_ 
           "SIZE: "&spl.GetDetailsOf(spl.ParseName(file.Name),1)&vbcrlf&_ 
           "LENGTH: "&spl.GetDetailsOf(spl.ParseName(file.Name),27)&vbcrlf&_ 
           "FRAME HEIGHT: "&spl.GetDetailsOf(spl.ParseName(file.Name),283)&vbcrlf&_ 
           "FRAME WIDTH: "&spl.GetDetailsOf(spl.ParseName(file.Name),285)&vbcrlf&string(50,"==") 
      Exit For 
     End If 
    Next 

Next 
objFile.Close 
set objFile = Nothing 
set files = nothing 
set spl = nothing 
set fol = nothing 
set obs = nothing 
set fso = nothing
