Duplicate files can be anywhere on your system; manual removal is tough.

This article may reference older System Mechanic® features that have been replaced or enhanced in the current version.

Clearing Duplicate Files

Nearly every user has them: two or more files with the same name containing the same information. Often called duplicate files, we’re not even sure how it happened. We create a document, add to it, change it or make other adjustments and save it. However, when we go through our list of programs and content, the same file name appears numerous times.

Flying under the radar

While redundant files are quite a common issue, they can often go unnoticed. Duplicate and unnecessary files can create a number of performance problems, not only causing the computer to carry out needless functions multiple times but dragging down the speed and operability of the machine as a result of it working harder to support these redundant files. While the computer’s operating system won’t be immediately impeded by redundant files, these items can cause your machine to take much longer to start up.

The damaging effects of duplicate files don’t stop there. These unnecessary files put a considerable amount of added stress on a PC, as the computer struggles to keep up. Over time, these files can overload the machine’s background functions and slow down the entire system.

Mislabeled issues

Even worse than not being aware of redundant files is attributing the performance problems caused by these files to another issue completely. Often, users will assume that their slow computer is operating poorly due to a lack of available RAM. Other times, people simply presume that their PC or hard drive is just getting old, and its slow performance is just the machine showing its age.

While these issues can no doubt cause performance changes, misidentifying a problem that’s actually caused by redundant files can cause users to miss a chase to speed up their PC. Instead of just assuming that the trouble lies with an old machine or not enough memory, users need to be able to identify and remove redundant files for PC tune-up to optimize the computer’s performance and save space.

How to Remove Redundant Files Manually

Actually locating and eliminating unneeded programs can be quite the undertaking if users aren’t armed with the right tools. Without using an external program, a user is forced to manually search for an identical file through their system’s default file browser (Windows Explorer on Windows or Finder on Mac). 

After that, they have to manually sort through the results and remove duplicate files they find. This isn’t helpful, of course, if you don’t know which files have duplicates. Going through a seemingly endless list of documents, software and other materials is a daunting task for even the most knowledgeable user. Thankfully, there is a better option.

Duplicate File Remover System Mechanic

System Mechanic is a PC performance solution that relies on patented technology developed with over 16 years of in-house engineering research. System Mechanic automatically cleans, repairs, and stabilizes Windows computers with a set of optimization tools that no other software has. For example, the built-in remover finds redundant files like unused multimedia players that may confuse and slow down your OS.

Instead of deleting all duplicates without user input, System Mechanic allows users to make choices about which programs they’d like to keep and which can be removed, all the while saving folks the headache of manually carrying out this process. By enabling the removal of unnecessary applications, System Mechanic can boost your available system resources by effectively eliminating many program conflicts. The result you’ll see is system speed.
