System resources are needed for every defragmenting operation. This can slow down your applications if you are defragmenting using other tools.
TuneUp Drive Defrag, on the other hand, puts the user first. If you start an application to work, play, or surf while TuneUpDrive Defrag is running, the defragmenting operation slows to release important resources for you. If no application is being used for the moment, TuneUpDrive Defrag continues defragmenting at the optimal speed.
Because TuneUp Drive Defrag:
arranges the files needed when booting Windows in an optimal manner so that the startup process runs as fast as possible
ensures that files and free disk space are contiguous (consolidation of unused disk space)
even handles large file fragments
defragments the main file table (MFT)
provides increased stability during defragmentation by means of sophisticated checks
