Do you use a dir utility like Directory Opus 4.17, or Ordering? Both are available on aminet for free. Dir utilities are very powerful and indispensible. This is another area where the Amiga shines above all other platforms (*nix has Worker, though).
A well configured Dopus installation can make this very easy. It has a command called GETDEVICES. It will list all real and virtual devices installed, if not listed, it's not there. With Dopus, you can copy & move files, deal with archives, edit the user-startup file, and much more.
These same things can be done in Workbench and AmigaDos. Do you have any Amiga mamuals? If not, these are some good titles to have on hand: "The AmigaDOS Manual", "The Amiga Companion" by Rob Peck, "Best Amiga Tips and Secrets" by Denny Adkins, the books that come with the OS or computer. To get the whole Amiga experience, everyone should have some of these.
I wish there was an archive or website that details the fundamentals of Amiga operations, but, I'm not aware of any. Anyone else?
Another beauty of Amiga is all of the published info about every detail of the OS and hardware.
