Let’s take a quick look at the manual way of how you can search for duplicate DMG files on your MacBook. This might go well in the beginning, but can a user ensure they continue to examine files at their best even after they’ve performed this job for a good while? It is most definitely a long shot by all means. Now we will briefly describe another downside of the manual method before we move on to the automated solution of finding and deleting duplicate DMG files on your MacBook.īy now you must have determined all the manual methods depend on the user to compare the files and judge if some/ all of them are duplicated or not. This was a neat little tip to further refine the suspected duplicate DMG files into a subset. But if the file size also matches bit by bit, this is most probably a case of duplicates and you should carefully review all the suspect files. If the files’ size is different, they simply aren’t duplicated and you can safely ignore them. If you’ve detected some files to be named the same way, you can compare their file size. This is, unless you can spare the time and energy of opening up each file and comparing it with the rest after they have been detected as suspected duplicates because of matching filenames.Īnd by the way, just to ensure there is an increased degree of objectivity and you do not mistakenly delete a file, we recommend you perform a second ‘step’ before making the final call on if 2 (or even more) files are duplicates or not. The reality might well be just the opposite, and so this method cannot be totally trusted upon at all. If 2 DMG files share the same name, this method determines them to be duplicate. This method is totally reliant on the filename. But this method of searching up duplicate DMG files has its own fair share of downsides. Once the whole list of duplicates has been compiled and presented to you, you have to give your verdict about any duplicates and move them to the Trash. dmg ) in the right place and let your MacBook dig out all the dmg files for you. It requires you to type in the extension (. įirst up is the easier, straightforward and moderately reliable solution.
This was just a brief intro about DMG files, now let’s focus on how to get rid of duplicate DMG files from your MacBook. DMG files made their debut from OS X 9, and have proved to be highly popular since then. Once the checksum has been successfully verified, only then the file will go on to decompress the data included inside it. Another key attribute of a DMG file is the checksum, which actually is the verification of the content’s integrity.
A DMG file is also known as an Apple Disk Image file, or a Mac OS X Disk Image file.ĭMG files are mostly used for storing the software installation media for a Mac, rather than the user requiring a disc. This is exactly the same as what happens with zipped files on a Windows computer system. It helps in using up less disk space than if the data wasn’t stored in a DMG file. A DMG file is used to compress and store data on a Mac.
