WinZip vs 7zip: First round – Misc Textual Documents

So, I was a lot closer to having this “mostly” working than I thought. After some trial and error with 7zips command line arguments I got a few good test runs in. I need to work with some different data to further confirm, but so far, it seems that 7zip is pure win!

See the text results below:

Testing Windows file Compression Utilities

So, after recalling a debate about which file compression utility was the best (WinRar vs 7zip, I think it was) I have decided to test this in the most accurate way I can think of. I am going to write an application that will run WinZip, WinRar, and 7zip on the same set of files, with the same settings (if possible, I haven’t looked at WinRar yet, but WinZip’s CLI is pretty sparse).

A few pages I found for reference:

• http://www.memecode.com/docs/winzip.html
• http://alonesworld.blogspot.com/2007/10/how-to-use-7-zip-on-command-line-prompt.html
• http://www.respower.com/page_tutorial_unrar

It seems that if I use the same files, run each from the command line through a .NET application and time it from start to finish, I think we can get some pretty accurate results. Check back in a little while and we’ll see what I come up with.
