File and Drive Defrag Tool – UltraDefrag

.

Almost a year ago I wrote about defraging drives from the command line.

I got an email from John that week:

“Hi Steve, I wanted to let you know about a free defragmentation tool. It is called UltraDefrag. It can defrag drives, Registry hives, and the paging file”

It took me a while, but I just checked it out – and it is a great tool.

Almost every feature of it can be called from the command line using the command line interface.

The drive and file defrag shows the blocks it is moving (Reminiscent of the old Norton defrag)

Ultra-Defrag

After your defrag is complete you can get an HTML report of its progress:

Ultra Defrag Report

If you want to scan files in use (Like the registry hives, and the paging file) you can enable a boot time scan:

Boot Scan

To show you how easy it is to run from the command line, here are some simple examples:

Defrag the C Drive:

udefrag.exe c:

Defrag C Drive

Defrag a specific file and folder:

udefrag C:\Windows\WindowsUpdate.log “C:\Program Files”

Ultra Defrag File Scan

Analyze all drives (Don’t defragment):

udefrag -a –all-fixed

Analyze Only

I am trying to defrag my hard drive without admin privileges. Is there any
way either registry or policies that can give the local user the privileges
to defrag their hard drive on their own? Any help would be greatly appreciated.

Hello Ramesh,

By its nature it requires full admin rights. This is because defrag needs to have low level access to the hard drive. I would say unless you have someone write a program to proxy it for you as an administrator…defrag must be run by a local admin.

One way around it would be to setup a scheduled task that ran at specific intervals, and then saving the admin password into the task. That way users without the rights have no need to call it (It is running in the background)
