7za to compress file(s)

I have a huge file that I wanted to compress, so I used the following to do so:

jay@pilsner:/tmp/3-jay$ ls -hla w*
-rw-rw-r-- 1 jay jay 5.6G May  9 10:51 wordlist.txt

The command:
7za a -v500m -mx1 archive.7z wordlist.txt

a = archive
-v500m = create 500MB chunks
-mx1 = fastest compression 


here it is in action:
