Extremely thorough and precise 5 stars by rocam13657 Apr 17, 2022
Highly recommended if you can afford the extra time it takes. show Review details
Good for novices, not for pros 3 stars by realbull2009250 Jul 19, 2013 (Read all my 60 reviews)
Piriform's Defraggler is good for inexperienced users, but definitely not for more experienced user's. Defraggler falls short on it's actual job purpose. It tends to be slow during big defrag jobs and doesn't do a thorough job. Many files were left fragmented after it finished. I had to use a different defrag program to finish the job. Defraggler is probably good for small jobs only. The inexperienced or average user may think it is great and be satisfied, but there are much better free defraggers available; Auslogics Disk Defrag, Puran Defrag, MyDefrag and Contig. show Review details
Works for me! 5 stars by rkfricks95 Jan 12, 2013
After 11 years of using (and paying for) Diskeeper, I have found Defraggler. Since I felt that Diskeeper was the best defragmentation option out there, there was no reason for me to look at any others. Within the past year or so (may be longer ago, I'm not sure) Condusiv acquired Diskeeper or they became the same company in some way. Since that time, I have felt that Diskeeper just wasn't/isn't the same quality as it once was. With that being said I tried Defraggler for free and am so impressed, I have upgraded to the "Professional" version. I am certainly not a computer genius or anything of the sort; but, I am a consumer of some software and Defraggler is one that works for me... show Review details
