For the moment I am using the following code:
The script part:

Dim fpdStartFilePath : fpdStartFilePath = "the string path"
Dim fpdStartDirPath : fpdStartDirPath = "" 'This does not seems to work at all
Dim fpdFilter : fpdFilter = "My custom filters for example (" & FileExtDlgFilter & ")|" & FileExtDlgFilter & "|"
Dim fpdOpenFileDlgTitle : fpdOpenFileDlgTitle = "Open a file of type " & FileExtDlgFilter ' This is the title of the dialog
Dim strFileToOpenPath : strFileToOpenPath = FilePickerDialog.openFileDlg(CStr(fpdStartFilePath), CStr(fpdStartDirPath), CStr(fpdFilter), CStr(fpdOpenFileDlgTitle))
If Not strFileToOpenPath = "" Then
	Dim strFileContent : strFileContent = FileReadContent(strFileToOpenPath)
	OrganizeContent(strFileContent)
End If

The html part:

<object id="FilePickerDialog" classid="CLSID:3050F4E1-98B5-11CF-BB82-00AA00BDCE0B"></object>

With such combination of VBScript and html (into a hta file) I get a full navigable Open File Dialog that allows me to:

• navigate throughout the integrated folder tree view and chose a folder to pick a file from (a single one);
• further filter the content of the folder by using the filters integrated into the columns headers;
• search for items with the Search function by typing a string into the relative Search text box
• pick a file;
• read that selected file content;
• elaborate the file content as I need to.

So it is an almost complete GUI: the limit is that I can't select more than one file at once: I haven't discovered yet if it is even possible to set a multi selection property to true for the dialog with such GUI object I don't know yet if it supports such selection mode. For the rest it works as expected opening the dialog and showing only the files that mach the extensions I need to be shown. Follows an example on how to set multiple file filters for the dialog:

Dim fpdFilter : fpdFilter = "HTML Files(*.html;*.htm)|*.html;*.htm|Text Files(*.txt;*.log)|*.txt;*.log|Image Files(*.jpg;*.gif)|*.jpg;*.gif|"

The syntax is a bit redundant but it allows to set a description that is shown for each option of the drop down file type selector and what is the relative value of each option that is the filter itself.
Notice that in order to work the string has to be converted by CStr as indicated into the following row of vbs code:

Dim strFileToOpenPath : strFileToOpenPath = FilePickerDialog.openFileDlg(CStr(fpdStartFilePath), CStr(fpdStartDirPath), CStr(fpdFilter), CStr(fpdOpenFileDlgTitle))

Of course it is possible to do the same in with JavaScript, by converting the given code accordingly with this language rules.
