Vbscript list all PDF files in folder and subfolders

Solution 1:

You'll want to use the GetExtensionName method on the FileSystemObject object.

Set x = CreateObject("scripting.filesystemobject")
WScript.Echo x.GetExtensionName("foo.pdf")

In your example, try using this

For Each objFile in colFiles
    If UCase(objFSO.GetExtensionName(objFile.name)) = "PDF" Then
        Wscript.Echo objFile.Name
    End If
Next

Solution 2:

(For those who stumble upon this from your search engine of choice)

This just recursively traces down the folder, so you don't need to duplicate your code twice. Also the OPs logic is needlessly complex.

Wscript.Echo "begin."
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objSuperFolder = objFSO.GetFolder(WScript.Arguments(0))
Call ShowSubfolders (objSuperFolder)

Wscript.Echo "end."

WScript.Quit 0

Sub ShowSubFolders(fFolder)
    Set objFolder = objFSO.GetFolder(fFolder.Path)
    Set colFiles = objFolder.Files
    For Each objFile in colFiles
        If UCase(objFSO.GetExtensionName(objFile.name)) = "PDF" Then
            Wscript.Echo objFile.Name
        End If
    Next

    For Each Subfolder in fFolder.SubFolders
        ShowSubFolders(Subfolder)
    Next
End Sub
