You may have downloaded some files and moved them to an external drive, but not deleted them from your Downloads folder. (Technically, this isn't true, because Time Machine uses hard links to indicate duplicate files, rather than storing multiple copies, but if you were to search a Time Machine drive for duplicates, these hard links would look like duplicate files.) Accidental duplicates are the files that you don't know are on your computer and can be located in more than one place. Or, you may store certain files you're working on in a folder, and then move them to an archive folder when a project is completed, but not delete the originals. Or, you may have transferred photos from your camera, and stored them in a folder, but also added them to your Photos library. Program for detecting and remove duplicate mac. And then later you may have forgotten you moved them and place them in a different location.

There's roughly two parts to this Mac Mini review. First part looks at the specifications and the second at how it performs in the real world with regards to creating graphics, photo editing and video editing. Configuration Apple's 2012 release of Mac Mini comes in three configurations: • • 4GB memory • 500GB hard drive • Intel HD Graphics 4000 • OS X Mountain Lion • • 4GB memory • 1TB hard drive • Intel HD Graphics 4000 • OS X Mountain Lion • • 4GB memory • Two 1TB hard drives • Intel HD Graphics 4000 • OS X Mountain Lion • OS X Server I bought the middle configuration but customised it with a 2.6Ghz quad-core and 1TB Fusion Drive. The set I'm buying is for mainly for photo and video editing, stuff that I do at home. Since I create graphics for newspaper, I'll also comment on its ability to perform under daily deadlines. I'm not really interested in numbers so you won't see much benchmarking - go to or for those.

I'm only interested in how predictable the computer is. Whether under stress will it start to show strange things, such as screen redraws, inability to switch from one app to another, missing palettes in software, inability to save files, inability to launch apps. I've an office computer (WinXP) with better specs than the Mac Mini but shows all those problems. Customisation of the Mac Mini is only available from the Apple store online.

Other retail or online stores are selling only standard configurations. The (non-exclusive) advantage of the Mac Mini is of course the ability to pair it up with your own display.

.third-party photo/video editing software, they offer a streamlined experience that will work well in It's used in every aspect of your computer's execution of processes, and you'll want a minimum of Additionally, this model uses an integrated graphics card which will be fine for this level of editing but.

Apple displays and that from the iMac are brilliant, but not excellent. If you work for print, and require colour accuracy for reproduction, you have to get a non-glossy screen. If you don't need that level of control over colours, the iMac might be a better buy. Personally, I prefer non-glossy screens.

I can't even stand the gloss on my iPad. If you're putting your computer facing light source or windows, there will be gloss. Processor The base model has a dual-core, the middle and server editions both quad-cores.

Not all applications take advantage of the multi-core. So depending on what you do, you might not spend more on the extra processing power.

Some applications that use multi-core: Photoshop, Lightroom, Aperture, Final Cut Pro, After Effects, Premiere Pro Some applications that do not support multi-core: Sketchup, iLife (includes iMovie, iPhoto, etc). If you're looking at the Mac Mini for entertainment, e.g. Watching shows on your HDTV, a dual-core model is sufficient. For computing needs and production work that requires rendering, I would recommend the quad-core.
