How do I join two .rar folders?

Some more file basics:

File names:
It's *vitally* important that you always include *everything* in a name.
1. You can't leave the dot blah off the end.
2. You can't leave spaces out (if they are in there to start with)
3. You can't change upper and lower case.

If you want to do something with a file name, then the best rule-of-thumb is 
to put it into quotes:
"my file from the Internet.avi"

So: I do *not* describe that file by:
my file from the Internet
"my file from the Internet"
"my File from the internet"

All of those are wrong. 

"The name is the name is the name. 
Every character exactly the same."

File paths:
If you are *not* in the same directory where your files live, then you need to 
use paths + the file name:
"/home/steve/my file from the Internet.avi"
Put quotes around the whole thing.

It's always easier and better to be in the *same* place as the files you are 
working on. So, use cd (change directory) to go there first.

File types - from the command-line:
When you want to know what *type* of file you have, use the file command:
file "my file from the Internet.avi"

It seems dumb to include the .avi there, but not all file names have the 
extension at the end.
