Like maybe if you have a 500 gig drive and you only have about 20-30 gigs free so you would use this and maybe free up another 2 or 3 gigs of space and maybe you will see a little bit of improvement there.
Getting rid of these files is not going to increase performance unless you are kinda of at a borderline. You probably have lots of different documents, you have photos, all sorts of different things on there. Now if you have those files sitting around is it going to decrease performance? The truth is you have tons of files for your Mac. So adding more empty space to your hard drive isn't going to necessarily increase performance. Well for virtual memory you might only use 10-20 gigs of that even if you are using an intense application. So for instance if you have a 500 GB hard drive, a pretty modest hard drive, you might have say a 100 gigs free. Now beyond a certain point you don't need that much. The more empty hard drive space the better your performance would be theoretically. So it is basically the sharing between the hard drive and the memory to get things done on your Mac. So things that you need all the time when you are running applications are in memory and things you don't need as often are stored in the hard drive. So you use the memory on your Mac when you run applications, and then you are using empty hard drive space to kind of expand that memory. Well in theory you are using empty hard drive space as a memory cache. So how can removing files from your hard drive improve performance. The common theme is that files you supposedly don't need any more it will go find them and remove them from your hard drive. Clear caches, clear logs, remove trash, remove universal binaries, remove languages, remove apps, remove left over app files. Here is a quick list of some of the items. So I went through all the different web sites for all the different cleaning programs and they all list almost exactly the same things that they do. Let's look at what they claim to do and why you really don't need them. I don't use any of these cleaning programs and never have. I use them with all sorts of applications all day long. I have been a Mac user for more than twenty-five years. People see all these advertisements all over the internet for programs that claim to clean your Mac and give you better performance. On today's episode let's talk about whether or not you need Mac cleaning programs. Video Transcript: Hi, this is Gary with MacMost Now.
