Question

Defragmenting - different analysis by 3 programs

Mar 10, 2017 10:13PM PST

Curious why Piriform Defraggler, Auslogics defrag and the built-in Win 7 defragmenter all show different levels of fragmentation? Is the built-in Win 7 adequate? Piriform is so thorough it takes forever to complete (I've never let it run to completion), Auslogics is full of PUPs (found by malwarebytes), and Win 7 only shows 1% fragmentation! Thanks for helping me understand and suggesting which to use.

they are different because if they defrag the same way, there will be copyright lawsuits Happy That is really about it. different companies gotta do things differently unless they purchase a license.

personally it let windows do it automatically. its been years since I done any manual defragging.

Unless your adding and subtracting a boat load of files it's doubtful you'll find running defrag very often to be of much value.

I use to run it every 6 months but I could not tell the difference before and after.

the built-in Win 7 is adequate .
Just set it up to defrag while you sleep.

I think I have defragged twice in four years and,(agreeing with Bob) , I have never seen any difference however as I don't keep much on the HDD as I ship most things to externals.

Maybe they have a different definition of "percentage of fragmentation"? Then they would report different numbers and all be right.

many thanks for your most helpful replies. Guess I was hanging on to very old (pre Win7) computer maintenance steps and can let that one go Happy all the best!
