This app saved me 9+Gb! Overall very helpful app. Problem with lack of directions manual; only FAQ which was not very helpful. Some features must be bought to be used (usually titled "Lite" with "Pro" including opening all features).

Well, which one is it? Developer's own description: "Free ($0.99)" Seems like another person doesn't know what "free" means.

Years ago, Windows was Windows and Mac was Mac. So I actually bought a Windows used computer to get the stuff limited to OS. I soon found out that Windows was horribly antiquated compared to Mac and offered little that Mac didn't. I tried Bootcamp when it came out, but, again, it's two computers -- pick one. Virtual Box allows me to use Windows machines like an application. It's wonderful. (But, the Microsoft Windows is outrageous in price: $384 for Vista -- Japanese version!) I salute and stand in awe of all the people involved in the development and updating of Virtualbox. Thank you, thank you, thank you.

Check the developer's site. This is not a free application; it is only a free download that you must pay to use!

Had to remove it because it took over my Macbook Pro (SL). Other use of the computer slowed until I finally gave up. Ran the scan 3 times and each time a dialogue said it was incomplete. I felt like it was a virus rather than an application. I also let it run all night and still had the incomplete dialogue.

Tried everything including email exchange with the developer. Every single backup gives a dialogue showing that there were errors. Backups are Gigabits and the app won't backup to drop box. Every notification at the end of backup requires looking at the console to see the errors log. After corresponding with the developer and following the suggestions given, there has been no change. Even though I bought the Pro version, it has never worked for me, so I uninstalled it today (I had hoped to keep the email on all my computers up to date without starting each one to download mail.)
