Surplus copies of photos, videos and documents can significantly slow your PC, phone and tablet. Robert Irvine reveals the most reliable free ways to find and delete them
Duplicate files don’t pose an obvious threat to your PC, aside from cluttering your folders with extra versions of documents, photos, videos and other items. But as they accumulate, they’ll have a detrimental effect on the speed and stability of your system, without you realising they’re to blame.
Not only do duplicates consume valuable hard-drive space, but they also mean your computer has to work harder to perform everyday tasks. Whenever it runs a malware scan, updates its search index or creates a backup, it’s forced to include these unnecessary copies, which significantly slows everything down.
Duplicates creep on to your PC in a variety of ways. You may have downloaded the same files twice, copied items instead of moving them, selected ‘Save as’ instead of Save, backed up folders to the same drive, or installed a program that cloned files without your knowledge – Windows even does this itself.
Most PC clean-up software such as BleachBit doesn’t detect duplicate files, because they’re not classified as junk, which means you’re probably not even aware of the extent of the problem. Thankfully, there are reliable ways to find and remove these pointless copies, but there are also plenty of rip-off tools to avoid.
In this feature, we recommend the best genuinely free duplicate cleaners, to rid your PC, phone and tablet of redundant copies, and make them tidier and faster.
