We can not fix "didn't work" - you need to provide full details like what exactly you did and what exactly did happen

The way  you delete a folder  is to right click on it in the sidebar which brings up a menu which has a line "delete folder" - click on delete folder

I guess I was afraid iPhoto might not be supported on future operating systems down the road.

That is correct - iPhoto was discontinued two and a half years ago and some day with some OS upgrade it will totally quit working leaving you with an emergency and probably very difficult transition to something new - it certainly is smart to move to Photos now since it is supported and is better in pretty much every way than iPhoto - it is new and does require learning and new work flows but it is far superior to iPhoto - these links will help with the migration process - : Links to User tips re migrating from iPhoto to Photos

Can the Photos app be deleted

No - it is part of the OS and can not be deleted - why would you wnat to anyway?

The Photos library can be deleted with no effect on the iPhoto library as I previously said

the two libraries are totally independent of each other

and as to

Do you know if the photos I deleted and trashed in iPhoto will also delete from the Time Machine backups on the next backup?

no - Time Machine maintains an archive of all old backups until it runs out of disk and then deletes the oldest ones to make space for new ones as explained on the TM preference panel  --  https://support.apple.com/en-us/HT201250

He said that the picture would download if I was on a different desktop, or if it wasn't already synced in my photos. :-/

That cannot be the reason.  My Mac is syncing with iCloud Photo Library, but I can still download all photos from the web interface at www.icloud.com, even if all photos have already been downloaded to the Photos LIbrary on the same mac.

Is your new Mac really running Sierra as show in your signature? Or is it running High Sierra?

It the photos in iCloud have been taken with an iPhone running iOS 11, the photos may be using the new HEIC codec. In that case a Mac with macOS 10.12. Sierra cannot  read the image files and videos, see:   Using HEIF or HEVC media on Apple devices - Apple Support

Which version of MacOS X are you using? If you are running Photos, you cannot be using an iBook G4.

If you are using a Mac with HighSierra an photos with iCloud Photo Library, you can ctrl-click an album in the sidebar and use the command "download originals" for the selected album.

Out of the box, you are limited to Favorites by pressing the period (.) key. 

I set up Keywords that I can tag photos with by pressing single keys.  Just as fast, and more sorting options to clear out the junk.

You only need the iPhoto library if you’re going to continue using iPhoto. Note that the media files are hardlinked, so deleting the iPhoto one won’t free up anywhere near 93GB of space.

Thanks yes sorry using Photos ... I should be able to sort this out now thank you again

As long as you have iPhoto set to copy the photo files into the library during import you can delete them from the Desktop after import, i.e. your iPhoto Advanced preference pane should have this check box checked:

Is it checked?

Also what system are you using?

You can move or delete it and you will not save much space  - Photos saves disk space by sharing images with your iPhoto or Aperture libraries - Apple Support  -  archiving it to you photo storage drive would be fine and then you would feel better

But if I go to About this Mac  and check on Storage it sure looks like Photos is taking up 169 GB and in Documents the iphoto library is taking up 98 GB, so I would say that moving the iphoto library to an external drive would save a lot of room on my mac.

Yes it looks like it uses double space because of the way hard links work - but as explained it does not

and again there is no connection of any sort between a Photos library and the iPhoto library it was migrated from - you can move or delete either with no effect on the other (note that when you move one it breaks the hard links and from then on it really does use all the space it reports it is using)

The article linked above tells how things work - basically the hard links are like this - the file exists on disk and two different libraries link to it - no connection between the libraries

and yes this is acurate

It is not accurate that the photo library is linking to it for the photos and that they are only on your mac once?

until you move the library, when you move the library you break the links and then each library uses all the space it reports (as described above)
