Question about which registry keys apply to which area of context menu

I'm trying to bookmark some shortcuts, and im about done - but im stuck on one location.

HKCR

Have * for files

Have Directory

Have Drive

Have Folder (would think thats synonymous with directory?) EDIT: apparently only applies to left pane explorer items whereas Directory applies to both left and right.

Have LibraryFolder (apparently thats libraries but requires elevation anyways and treated separate from folder or directory)

The one im stuck on its meaning/application relative to the others is AllFilesystemObjects. What does this apply to? Trying to label these in such a way that its clear to me for the long term :P

This is what I've found:


'Folder' includes Directory+Virtual folders+Drive

Boy they sure know how to make things convoluted lol. Still - seems to illustrate it well enough. Now to get that into short, concise, understandable text I can reference some odd months down the line after I’ve long forgotten

Thank you!

You're welcome. Good luck with the text. I guess you could convert all that to set notation. Set Symbols
