Defraggler by Piriform

Defraggler is a free disk defragmentation program released by Piriform with enhanced features which allow you more options to increase the ‘speed’ and productivity of your computer. Other defragging programs (such as the one that is built into Windows) only allow you to ‘defrag’ a whole disk at once (which can be laborious and time consuming).

Defraggler has a quick defrag if you want to save time or there are other options such as the ability to defragment an entire file, a folder, or a single file. Tell Defraggler to search for files of a particular size or type. Or tell it to exclude files by name, file type as well as  other criteria. It also organises free disk space helping to limit further fragmentation.

A really good feature is the ability to move large files to the end of the hard drive. Your PC will access files faster if they are at the start of your hard drive. This programme has the ability to put the large files you probably don’t use that often at the end of the drive so that Windows can seek and access the smaller files with increased speed and efficiency.

The programme is very small to download and install (typically 3mb) and due to its configuration runs really resource light meaning you can carry on with tasks on your computer without having a ‘laggy’ machine whilst the defrag service is running in the background.

The reviews below show just how good the programme is

“… you can choose to defragment individual files – Defraggler is one of the few programs I’ve seen with this capacity – and focus mainly on those most in need of immediate attention… Past free offerings in this category did not have the speed or features of Defraggler. I now count this as one of my must-have utilities.” The PC Guy –

“Defraggler will show you all your fragmented files. You can click one to see where on the disk its various pieces lie, or defragment just that one. This can be useful when dealing with very large, performance critical files such as databases… Piriform Defraggler is free, fast, marginally more interesting to watch than the default, and has useful additional features. What’s not to like?” PC World
