Pendrive paste option is not showing in mac?

How can I copy and paste content to pendrive in mac. I can not see paste option there for pendrive.

There is a very easy to use pendrive in mac system. You would have faced this type of problem with a pendrive formated as NTFS. You just need to reformat your pendrive and choose the option as FAT32 and now it will be ready to use with mac as well as windows operating system.
