从文件中获取扩展属性

Question

我正在尝试从运行脚本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

一旦我可以添加其他文件，我就会尝试获取文件名和长度。

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

我通过在 Windows 7 中的 Windows 资源管理器中双击 vbs 文件来运行该脚本。

该脚本运行时没有错误并返回文件名，但不返回扩展属性。任何帮助将不胜感激。

以下代码能够获取 mp4 文件的名称、大小、长度、帧高度和帧宽度等详细信息。对于flv、avi、mkv格式的文件，只能提取其名称和大小。对于这些文件，即使右键单击它们，选择属性并转到“详细信息”选项卡，您也不会看到有关其长度、高度和宽度的信息。但对于 mp4，您可以看到所有这些细节。

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
