I updated my profile, I suppose it has been so long since I've logged in that it was lost in sketchucation updates or something.

Not sure how to "print" a file tree, but everything is working ok now. I just was able to execute the rounded corners on a part to be printed on my A8, so all the Fredo6 stuff seems ok. If you want to pique your memory on the SU7 in win10, I'll try to generate the file tree, otherwise my questions have been answered .

It has been perhaps 10 years ago when I loaded SU7, but I think I did use the loader. It seems that for what ever reason, windows 10 (and 8 before that) looked for sketchup directory, and didn't find it in the google directory. With SU7 in it's own directory at same level as the original Google directory, when I click on a file it gives me the choice of SU7 and SU2013, so I think that part is ok. AS I said, once i got the icon path right I found the correct instance and all the new plugins are in place.

Ok, The folders look the same. Maybe I just have to reload the program after rebooting the PC, I have found that to work sometimes in the past.

One thing, Does the Fredo6 tools have its own menu? How does it look on screen? Maybe I have it and just don't know it!
edit:
Well, I feel stupid, I have 2013 loaded to allow working with newer files I find online. It runs too slow on my machine which is one reason I stay with 2007 v7. Anyway, it defaults as the program to open .skp files for some reason. my v7 sits in a Google directory, so I guess it is invisible to windows for loading. So, I copied a duplicate SU7 into it's own directory. However, the icon on desktop still points to the one in google directory! I have been adding stuff to the other one, but clicking on the icon and not finding anything. I just Created a new icon shortcut, and now all the Fredo6 stuff it right there where it should be!

Thanks for the help anyway!

OK, thanks. All the Fredo6 .rb files and the associated folders are in plugins, but should I move sketchup.rb and extensions.rb into the plugins folder? I guess i'll try it and see. I'm not sure what the difference is between the "tools folder" vs. the "plugins folder". In the past I have put each new plugin .rb file in the plugins folder and they all seemed to load and work ok.

I am using V7.1.6860 ( yeah, I know, ancient but it does what I want in designing my foamie airplanes and 3d print parts). Just downloaded the legacy versions of the fredo6 files (tools, lib, and round corner) I found that my version (apparently) won't find the rbz files in the extensions box. So, based on some of the other comments I renamed them to .zip extensions, and extracted them then copied them into the plugins folder. When I power up SU, I don't find any of them in menus or icons. I noted in looking at the fredo6.rb that it requires sketchup.rb and extensions.rb. I found them in the tools folder, not the plugins folder. Should I put all the fredo files in the tools folder? Also, when I extracted each of the zipped files, I got a .rb file and a folder. I put both of them in the plugins folder for each of the three operators. So, again, should I be using the tools folder, or plugins, or both?

Thanks for any help!
