True Launch Bar v6.6.5 beta

This problem with the toolbar folder - it is not "true" portable. By default TLB uses the folder %appdata%\Microsoft\Internet Explorer\Quick Launch
Also it is possible to swich into any other folder outside the profile, so reinstalling windows will not take effect to this toolbar folder.

But I guess the "true" portable way is keep toolbar folder inside the installation. I guess I'll add the folder "toolbars" into portable package and all subfolders will be listed in the "Switch toolbar" automatically.

standalone1.xml (why is there this one??)

Not sure but looks like you've tried to select the tlb installation folder as toolbar folder and make a copy of file (drag&drop).
