I don’t understand your first question; FreeARC and KGB are both archivers, so yes, they “do the same job.”

As to your second question, the answer is yes. If you read the thread, you will note that I was replying to a user who related a Google search as though it proved the prevalence of archive corruption. My response was intended to demonstrate PRECISELY the point you’re making.

I don’t use DURILCA. It takes too long; it is impractical. But KGB is also impractical.

I will state again that FreeARC is the clear winner.

As for your second point, you do realize that the more famous you are, the more hits you’ll get, don’t you? I don’t mean nothing by it, but I’ve heard of KGB before, but I didn’t heard of DURLICA…
And also, look at this:
If I do a search for “zip corrupted archive” I get this
About 943,000 results (0.25 seconds)
So… Sh*t will happen to archives… :)

Bottom line: for standard use archiving, FreeARC is the clear winner. For your SPECIFIC use, something else may work better (and be worth your TIME!) but it’s rare that anything I’ve used beats FreeARC, though it has happened. FreeARC wins hands-down in every category overall with Ultra compression.

KGB sucks. This must have been this blogger’s first experience with anything other than WinZIP.
