IObit has shipped Smart Defrag 5, a major update of its freeware disk optimizer. A new defrag engine supports multi-threading for maximum performance.
New defrag types allow users to focus on large files only, or to consolidate free disk space. If you’re unsure which defrag type to use, IOBit’s Smart Defrag/Optimize Technology will intelligently select if for you.
Elsewhere, defrags may now be scheduled to run when you’re not around. And just in case the program still gets in your way, Silent Mode automatically cuts resource use when full-screen tasks or specified processes are running.
The Pro version has gained an option to defragment specified files at boot time.
The interface has been revamped for more intuitive operation. And a new "Readable" skin makes it easier to, well, read.
Smart Defrag 5 is a free tool for Windows 2000 and later.
