It's an easy-to use application, you can install it in less than 5 minutes without problems with any Mac computer (even if this one has very old hardware). The most important thing I like about Daisydisk app are its intuitive interface as well of course all those features! Sometimes when i have some issues or there isn't enough time between backups then sometimes my clients complain because they find errors which were not created by me but just normal user activity such deleting files accidentally etc.. So please try once firstly before using your money otherwise after few month maybe someone will ask back from them how their backup system works? You should think twice at least 3 times what exactly do YOU need so don´t be afraid too much cause these softwares make people feel safe even though nothing really happens unless we want something bad happen ;) And yes sure no other software provides more useful information regarding our data storage devices status compared only daisydisk does!! It's easy, it's fast and it can be used to find out where your hard drive is taking up all your space. It's not cheap but you will get your money back in no time. I've been using this software for almost a year now and haven't had any issues or problems with it. If you want a quick way to get an idea of how much space different folders have taken up then use DaisyDisk. I have been able to quickly identify which folders are taking up most of my hard drive space so I can delete them.
