|You can copy and paste with a single click from Windows Explorer.|
To copy a group of files highlight the first file. Hold down the shift key and click the last file in the group. All files in between will be highlighted. You can them Right click on the highlighted files, copy and paste the whole group into a single folder.
Or you can highlight individual files by holding down the shift key and clicking each file in turn then Right click on one of the highlighted files and copy and paste all highlighted files.
All the source files must be in the same folder and the destination can only be a single folder. You can do the same thing with folders and all files within the highlighted folders with be copied to the destination using the same folder names,
So with a single paste you could copy the whole contents of a disk to another disk if the destination is big enough. The problem with this approach though is if an error should occur such a file is read only, then the paste will terminate with some files copied and some still..
