Hi

I am really new to this and I believe this is going to make a lot of you sigh. However I made a small script to list subfolders and files within a folder.

The script works however I don't understand why some of it does. Here is the script:

Option Explicit

Dim objFso, strUserInput, objFolder, foldl, subf, file

Set objFso = CreateObject("Scripting.FileSystemObject")

strUserInput = InputBox("Please enter the path of the folder you wish to find " & _
     "for example c:\windows\system32")

If objFso.FolderExists(strUserInput) Then

Set foldl = objFso.GetFolder(strUserInput)

For Each subf In foldl.SubFolders      < How does the script know what subf is?, I have declared it as a variable but thats all it is an empty variable

WScript.Echo subf.Name

Next

For Each file In foldl.Files    < I have the same question here, why does it recognise file as a file object, when all I have done is declared it as a variable

WScript.Echo file.Name

Next

Else

WScript.Echo "No"

End If

I have put my questions by the parts of the script I don't understand. I don't understand why the script recognises that subf as a subfolder or file as a file. I have only declared them as variables and not given them values.

If someone could explain I would be most gratefull

You are working with Collections, and appointing members of the collection to subf and file, VBScript will then store each member of the collection in that variable.

For Each subf In foldl.SubFolders

in the above line the subf acts like the iterator.
Instaed of doing a for i = 0 to foldl.subfolder.count
you are using the subf
so to access items it is doing a subf rather than foldl.SubFolder.Item(i)

or something along those lines.

This code is not tested just shown as an example of why it works.

I really hope this makes sense!

Edit:
Apparently I am not the quickest poster.

Thanks very much both of you. That was really fast and it helped me loads. I want to understand why it works or doesn't for that matter.
I am much obliged to you
