Is there a way to copy files between drives via Ubuntu GUI?

First I can’t open my other drives. There’s an error unknown filesystem type 'exfat'. I solved this by installing exfat-fuse and exfat-utils. Now I can open my other drives.

But now I want to copy files from my Ubuntu drive partition to the other drives via the ubuntu GUI, but I can’t copy it. The paste command is disabled.

I know there’s a command line way to do this, but I want to do this via GUI. It’s faster to do this via GUI and I don’t have to memorize commands.

Is there a program that I can install to make this possible?
