Alternative of diskview

about Defraggler and DiskView Jan 2015

I am looking for an alternative app to Diskview in the Windows Sysinternals Unities package or the drive map of Piriform Defraggler. The features that I am looking for is highlight location of specific file or files in the specific folder on the drive map. Anyone know which software have that feature?


Defraggler also 'benchmarks (?!)

On my latest version, it has other functions & properties not mentioned in the main topic. Unsure how the disk benchmarks compare to other programs or the 'real world'. Benching is a complex business.

Fast, and I like that it can i.e. close or hibernate computer after complete defragmentation.


Apart from a lack of a Defrag optimizer, it's excellent.

about Defraggler and Auslogics Disk Defrag Jun 2011

Would like to switch to Defraggler from Auslogics Disk Defrag however one thing preventing me is a lack of a Defrag optimizer. Apart from this I think Defraggler is an excellent app.
