You can drag files in a virtual machine directly onto Mac applications. You can drag Outlook attachments from a Windows virtual machine to your Mac. You can also drag images between Windows applications and Mac applications. You can move text by copying and pasting or cutting and pasting.
You can drag files and folders to move and copy them between your virtual machines and your Mac. Now if you want to copy text using the clipboard, that works between the host and each supported virtual machine with the tools installed as noted in Moving and Copying Files and Text Between Virtual Machines and Your Mac When moving files between VMs Drag and drop is the feature to use (where supported with VMWare tools, etc)in order to move files from the host computer to each guest VM and the opposite is true too. If you are trying to copy and paste files using a right click and copy command in the Finder, and then trying to right click and paste in a Windows VM for example that will not work since VMware does not support copying files that way. Yes Copy and paste is supported, but it depends on what you are doing.
