"files ready to be written to disk", do what? on recpt ...

[Boswell]

I receive this message when clkng; 'copy files to E:', ('send to' menu)

 

[Andrew Murray]

Drive E: sounds like your optical (DVD/CD) drive.

That message comes up when you "send to" your DVD or CD drive. It just
indicates there are files ready to be copied to CD/DVD.
