Since this is such a basic, yet vital, utility, I have spent years looking for the ideal clipboard manager, and for me it is Ditto. It is gratis including for commercial porpoises.
I would recommend first clearing the clipboard – launch Ditto, hit Ctrl-A to select all, then hit the delete key, or right-click and select delete.
Now, make all your selections to populate the clipboard, and finally, launch Ditto, hit Ctr-A, then Ctrl-C, navigate to where you want to paste and hit Ctrl-v. I have just tested this and it works.
Easy peasy, plus Ditto is the best clipboard manager that there is.
•Easy to use interface
•Search and paste previous copy entries
•Keep multiple computer's clipboards in sync
•Data is encrypted when sent over the network
•Accessed from tray icon or global hot key
•Select entry by double click, enter key or drag drop
•Paste into any window that excepts standard copy/paste entries
•Display thumbnail of copied images in list
•Full Unicode support(display foreign characters)
•UTF-8 support for language files(create language files in any language)
•Uses sqlite database (www.sqlite.org)
and many more features. My favo(u)rite is sticky clips. Ditto also happens to be open-source and can be used as a portable application too.
In fairness to the other suggestion, you might want to read Clipboard Master vs Ditto: Comparing 2 Cool Windows Clipboard Managers and make your own choice.
Although, this page says
As good as it is, the user interface of Clipboard Master is not the
best and as a result, there is a good amount of learning curve to get
used to Clipboard Master.
Wrapping Up: Best Clipboard Manager for Windows
We saw some of the best clipboard manager tools for Windows. If you
are looking for freeware that just works, Ditto is a good option. If
you need a clipboard manager that sync between your Mac and Windows
PC, 1Clipboard should work. Or for more sync options i.e. Android and
iOS, try Clipboard fusion. Though that comes with a price tag of $15
Finally, if you are someone who likes to install one app that does
everything, that Clipboard master is a better choice. The free version
comes with screenshot capture and text expander option along with
clipboard manager. But on the flip side, it doesn’t have the best UI
I suggest waiting until all answers are in, then reading reviews of them all and taking them for a test drive. You might also want to consider whether you will swap over to a new clipboard manager, or stick with your existing one the majority of the time, and only use one of the answers here for special circumstances.
