I did a quick duplicate file scan on one of my Windows 8 machines, and found duplicates for an assortment of additional reasons: These are sometimes considered duplicate files – at least in name – though there are often many files that actually don’t change from version to version and may qualify as true identical duplicates. If you’ve updated Windows and have a Windows.old folder, the previous operating sytem copy will be there. While that’s no longer the case with recent Windows versions (a hidden partition is now more commonly used), manufacturers and others still occasionally keep a duplicate copy of the operating system installation media on the hard disk. 
In older versions of Windows, the original installation source was duplicated in a folder called “I386”. When such changes are detected, the files are restored from duplicate copies.

If program “B” also uses this exact same library, there are two approaches that could be taken: This happens quite legitimately for a variety of reasons, which mostly boil down to programs not wanting to put themselves at risk due to the bad behaviors of other programs.įor example, program “A” installs a copy of a library of shared code. #WHY DID PHOTOS FOR MAC DUPLICATE ALL MY PHOTOS SOFTWARE#
Done incorrectly, you can quickly render your computer unbootable.ĭuplicate files happen for a number of reasons, and surprisingly, what you and I do isn’t at the top of the list of the most common causes.Īs I mentioned in a previous article, it’s not at all uncommon to have multiple copies – often identical copies – of files that are used by the software installed on your machine.
