Using patterns - capture text after a string

It is my first time to use patterns for capturing objects.

I cannot figure out what goes into the pattern in order to capture everything after "Details : Folders: ".

Example:
Cell value: Details : Folders: f1A795, f1B795, f2A795, f34955, fK683
Output: f1A795, f1B795, f2A795, f34955, fK683


My code below omits the first "f" and gives me this result: "1A795, f1B795, f2A795, f34955, fK683"

Set r = CreateObject("VBScript.RegExp")
    r.IgnoreCase = True
    r.Global = True
    r.Pattern = "[\Details : Folders: ]+"

Can you help?
