How can I enable Windows Explorer (Windows 7 64 bit) to open LabView 8.2.1 LLB files?

Just to be clear, the added explorer extension that previously worked years ago would allow you to double click on an LLB file, in Windows Explorer, and would display the VIs in that LLB still in an explorer window.  From there you could do normal File operations on the LLB as if it were something similar to a zip containing a collection of files.  All of this could be done without launching LabVIEW.  The screenshot you are showing is just a folder in Windows which contains a bunch of VIs.

I believe this is what the OP was refering to.

Oh, I see. My mistake. LV 8.5 does not even have the “Enable Windows Explorer for LLB Files” option in Tools/Options/Environment. But what's the problem with opening the LLB in LabVIEW? Isn't that what one usually would want to do?

It's a work flow thing I guess.  If I'm renaming files on disk, or re-arranging the file organization I'm going to be doing it in Windows Explorer.  If an LLB can be just seen as another folder in my OS, then that means I could do more file operations, in a familiar file management tool.  Rather than the LLB manager which is only ever used on LLBs, and for me that's like twice a year, where I usually have 20 explorer windows open at any given time.

I would recommend that you get rid of the llb's altogether then and convert them to a folder. They have always been somewhat fragile and incompatible with source code control.
