Some programs, like browsers, have special commands that clean their temporary files, cookies, history, and so on, but such commands have to be run manually every time the user closes the program. Such files can be deleted or cleaned without harming Windows' performance. Windows and its various programs consume a large amount of storage space for theirĬaches, temporary data, and service files. Even for conventional hard drives, which are much larger in capacity, this still may be an issue especially when they are installed in computers used for massive data processing tasks like heavy gaming, multimedia production, and desktop publishing. As a result, free storage space is always scarce for SSD devices. Even a quite powerful laptop may have an SSD drive of only 128 GB. They are fast and shock-resistant, but they have one serious drawback: their capacity is relatively limited. I have not tried so I do not know.Many modern computers use SSD drives as their primary storage devices. Method 2 might not work using internet recovery, It depends if the data used to initialize functions of the internet recovery is stored on the HDD, if so, reformatting it could mess with it. Note: Method 1 is probably the safest and easiest option. This will reformat EVERYTHING on the disk, restoring it to a single blank partition ready for a fresh reinstall of OS X, so as with everything like this, be sure to backup accordingly and make certain you have a method of reinstalling OS X which is not reliant on the HDD. Install from an OS X Pen Drive, open disk utility, but instead of where /u/5HT-2a said "Select your partition", select the drive itself and choose to reformat the whole thing as Mac OS Extended (Journaled). You can now follow the steps given by /u/5HT-2a to reinstall, or use an OS X install disk. Now click the restore option to restore you HDD to a single (Mac) volume. Select the tick box that says "Remove Windows 7 or later version" then click continue. Open the Bootcamp assistant app in the "Utilities" folder. I'm assuming your Mac has one HDD that you installed windows to via bootcamp? There are a couple of ways you can remove the bootcamp partition, restoring the HDD to a single volume, and do a clean OS X install:
