Mac computer HDD Cleanup skills

　　 A variety of techniques for HDD cleaning of Apple Mac computer

1. Exit and reopen the application

Many other applications, such as Safari Explorer, Chrome Browser, Photoshop, and so on, create a lot of temporary cache files at run time. If you have not exited these applications for a long time, these cached files will continue to grow and generally will not be purged (until the application is exited).

Of course you can also delete the cached files manually, but it is much easier to reopen the application. Let the application handle it for you. This approach is especially effective for browser applications.

2. Reboot Mac, install system update

Although we rarely reboot the Mac, I would like to point out that restarting the Mac can release considerable disk free space. Restarting the MAC computer refreshes the system cache, cleans up some of the application's caches, installs system updates, and perhaps more significantly clears both: The Virtual memory Exchange file (Swapfile) and the Sleep Mirror file (sleepimage). If you rarely reboot your MAC, the two can become very large. When a MAC computer restarts, the two files will be purged, and in the following example, these two temporary files occupy gigabytes of disk space.

So it's a good idea to restart the MAC computer after a while, even if it's only once in one months. You can also install OS X updates. When it comes to system updates, if you've already downloaded them, you're not installing them, they're just sitting there and hogging the disk space on your Mac computer. These system updates are hundreds of MB in size and several gigabytes (GB). So it's time to restart your Mac computer to get these disk space back and install the updates.

3. Clean up the Downloads folder

The "Download" folder is "notorious". I usually don't care, after a while, the contents of this folder will be very much. Go to your appropriate folder (~/downloads directory), sort the files by the amount of disk space you want, and then delete any unwanted files.

So I want Mac users to get into a good habit: Manage the Downloads folder. In general, after installing the application, delete the installed. dmg file, after extracting the file, delete the original compressed file, and regularly archive the usual files.

4. Empty the Waste basket

Sounds obvious, right? But it's easy to forget. The waste basket will continue to "grow" after a period of "growth", and sometimes the Mac doesn't have enough hard disk space just because a lot of things have been moved to the trash, but in fact, these things are still on your disk. If you rarely empty the trash, immediately right-click on the Trash icon and select Empty Trash.

5. Use "Cleanmymac" software to clean up space

Cleanmymac is a very famous Mac Disk Cleanup software, can help you automatically scan your Mac, to find out the user cache files can be cleaned, system cache files, system log files and other system garbage, in addition it can help you find the machine of large files and infrequently used files, As you wish to do the deletion, Cleanmymac's own utility with the uninstaller function is also very practical, can help Mac users completely uninstall unwanted applications, no residue, more efficient release of disk space!
