Scripting shouldn't be needed for either thing, unless you have additional requirements.
TBone's already given a good answer for the folder part.
For the file part, the How to Create New/Empty Files FAQ shows ways to create empty files in Opus (no need to use FSUtil.exe). Just add {clip} to one of those commands to make it use the clipboard as the name. There are several different commands there, depending on whether you want the option of typing a new name or editing the file straight away.
(I've renamed the thread, since "Help with script!!!" was not very descriptive.)
