I found a program that zips a file much better. It's called 7-zip. Lords 1.505 are compressed with that new program so they are "only" 121 MB instead 160 MB in classical WinRaR. To exctract you don't need anything new, just WinRaR. When the Lords 1.505 unrars they are 500 MB.

If you have any problems to unRaR use this program. It's freeware.
