Everything about Defraggler

Defragmentation utility for Windows

Defraggler is a formerly-supported freeware defragmentation utility developed by Piriform Software, which can defragment individual files or groups of files on computer memory systems. Defraggler runs on Microsoft Windows; it has support for all versions since Windows XP. It includes support for both IA-32 and x64 versions of these operating systems. In September 2026, Piriform announced that Defraggler had reached its end of life. It is no longer hosted on Piriform's website, and all download and support pages for the product have been removed.
