[alt.sources.amiga] Compression

presley@oahu.cs.ucla.edu (Matthew Presley) (09/14/90)

To the person wondering about compression and
uuencoding here is a brief synopsis.

Uuencoding changes a file from binary to text.
Uudecoding changes a uucoded file back to binary form.
This is used to send files through mail servers.

Thus, if you have a filename ending in uu, then 
you should uudecode it.
	e.g.  foo.Zuu
			foo.zuu
			foo.uu
			foo.lzhuu
			foo.lhwuu

Once decoded the file will most likely be a binary
compressed file.  The too most popular compression
formats for the amiga seem to be zoo and lharc.

A zoo file has the form foo.zoo
A lharc file has the form foo.lzh

You should use zoo to extract the zoo file
and lharc to extract the lharc files.

Other compression schemes are:
	arc
	compress
	lhwarp
	warp
	zip
	pak

There are programs for each of these compression schemes
There are suffixes for each scheme. 
If you need any of these programs just drop me an email.
They are all public domain.

Also if you have files like the following:
       
                   filename.zuu1
                   filename.zuu2
                   filename.zuu3
 
On the Amiga you want to to to the join command:
     
 join filename.zuu1 filename.zuu2 filename.zuu3 as filename.zuu
  
And on a unix system you want to do the cat command:
  
 cat filename.zuu1 filename.zuu2 filename.zuu3 > filename.zuu
 
Before you UUDecode them.  :-)

Before joining (concatenating) files,
before decoding files,
BE SURE TO STRIP USELESS MAIL HEADER GARBAGE!
This will be at the start of each file (if at all).

He says with a .signature tacked onto the end of his post. Look out 
and strip those, too.
