Find and delete duplicate files with MacKeeper

Do you have duplicate files on the disk drive in your Mac? It is a fairly safe bet that you do. It can easily happen and somtimes you copy a file to a new folder to work on it or include it in a new project, you might download a file off the internet a second time, forgetting that you have already done it, you might copy files off a USB flash memory drive into a different folder than last time, and so on.

Duplicates build up without your knowledge and they add to the clutter on the disk drive, they waste space, and they can affect the performance of the Mac. Deleting any duplicate files will free up the disk space they occupy, which can be quite significate if there are duplicate movies, and help you to organise your files better.

MacKeeper will scan the disk drive and list all the duplicate files making it easy to see what is duplicated and where the files are stored. It's not the only utility that can do this, but it's a useful app to have because finding duplicates is just one of many functions in this handy toolkit.

Start MacKeeper and click Duplicates in the left-hand panel. It will then start scanning the disk drive. When it has finished you will see the total disk space occupied by duplicates in the left panel and on the right is a list of the files.

There is a little triangle next to each file in the list. Click it to expand the entry and see all the locations of the duplicates. Quick Look is available and if you want to check that two files really are the same you can select one and click Quick Look to view it.

Go through the list of duplicates, expanding each entry, and tick the box next to the ones that you don't want to keep. When you are happy with the selections, click the Remove button to delete them and free up the disk space they occupy.

Well, actually it doesn't free up disk space - the files are moved to the Trash. This means you can recover files if you discover you really do need a duplicate. Empty the Trash if you are really sure you don't want the files and then you'll recover the disk space.
