Don't buy into this con. Most of the people posting above have only posted once (except Jouri Serdioukov), and the way it reads, it looks like the same person is just answering themselves under different user names.
The truth about this program...
The program is not fully free like they are trying to claim. The most basic of functionality might be free, but the moment you want to put all your emails into separate folders that is a paid feature.
The program is not easy to understand nor is it easy to install. You install the first program, which inside that it then links you to an advanced option that needs to be downloaded and installed to get usable features, only to find out you then need to pay for those features.
The video help link takes you to YouTube video which shows something completely different to what you see on your screen, and appears to be of some advanced feature you don't have unless you pay.
I had to uninstall the advanced version which overwrote the basic version, and then had to reinstall the basic version.
I then exported the personal folder (can't export a PST without paying) to a single EML folder. It did appear to export all the emails into one folder, so I will give it that, it didn't do a 10 email limit like the others, but you are definitely not getting some free fully featured program like the above posts try to elude to.
