How to Handle SSD Drives in Defraggler Suggestions Posted 2 hours ago · Report reply If you have 50,000 files on your SSD then 500 fragments is just a rounding error. If you have one file with 500 fragments, that's another matter. If you're on Win 8 or 10 and if you have Sys Restore enabled, and fragmentation is greater than 10% (whatever that means) then Windows Defragger will defrag your SSD once a month. Before anyone says this is an Optimise, it is in Microsoft's words 'a 'Traditional Defrag'. This is apparently to manage the fragmants in volsnap files. Does Defraggler replace Defragger? (I'm not a Defraggler user.) Unless you have many fragments in one file (say 100+) and you use that file frequently, then forget it.
