Zip program compression

post #1 of 6
Thread Starter 
I have both 7zip and Win Zip and was wondering how to set it up for the smallest compression. Is there actually a danger zone when compressing files?? Can you compress too much and risk damaging the file?

There is no way to compress too much. Compression as performed by archiving utilities only removes redundant, empty, or easily patterned data. Everything will return completely intact in the end.

So how do you know if you have the best compression?

They only real way to know whether or not you have the best compression for your file(s) is to use several different methods and compare the results. Different compression methods use different techniques to compress the data, but the one thing they all have in common is that they depend on how the file(s) is/are structured. So just because one utility compresses "file.x" better than everything else, that doesn't mean it will compress "file.y" better. That said, 7zip and zip are usually pretty safe bets when it comes to compression size.

Also keep in mind that more compression is generally traded for slower compression/decompression speeds.

Hope this helps!
