That's absolutely right. It was ok back in the days where webspace was kinda rare and bandwith was small. I think everyone who wants to download an ISO nowadays will not care for 50MB extra just to save himself the trouble of unpacking and possible messed up contents.

What about uploading? I have uploaded almost 600 Gb to 4shared. I think you can do the math...
BTW, I don't use ecm any more.

Imagine the time it takes to (i.e.) ecm and ISO and then RAR it up with maximum compression... on my computer I think I'm faster in uploading 50MB than in saving. Compression without compression ( ;) ) doesn't even take 1/3rd of the time.

I've stopped using ecm as well, with 132kb/s up and only about 5-7 minutes for any iso (dvd is not counted here) to max compress in winrar or 7zip. It's just not worth it anymore.

I strongly consider to switch to NanoZip as soon as it's stable. Unfortunately, it looks like this will take a while.

On the other hand, WinRAR is close to become v4.00, which is a good version to introduce some improved compression. Let's see what they will do.

Right... if I'm not mistaken, the last change in algorithm was while introducing v3.0. Would be awesome if they had something better. Well, I still prefer free tools but in the end, (win)rar is some nice-to-handle tool :P

Ok I'll phase out ECM too then. Although I'm not quite convinced it is broken :P I might just switch to good old rar+sfv or something.

OK, the first beta of WinRAR v4.00 is now out. Unfortunately there is no improved compression, only decompression is faster. Not what I expected :(

That's too bad. Let us hope that the author of NanoZip makes more head way on the stability of the program.

Yeah, let's hope so, because almost one year between the last two alphas is :x

I use both. 7-Zip for general images and WinRAR for the ones with audio tracks.

Due to the fact that 7z format doesn't support recovery record, I also use WinRAR in the case that I will upload the file to online storage sites.

However, I don't know what to do with WinRAR's advanced compression parameters, I follow a guide I read years ago on a PC magazine but have no idea whether it is the best. Does anyone know how to change this setting to archive best result?

My maximum compression profile:
