JkDefragGUI

JkDefragGUI is an application that allows you to perform a defragmenting task on your hard drive.
The software doesn't need to be installed and leaves your Windows registry keys intact. This means JkDefragGUI is actually portable and you can place it on an external device and run it on any computer.
The user interface is easy to navigate through. In the "General" tab you can select an action (e.g. analyze only; analyze, defragment and fast optimization), set the debug level (e.g. warning messages, fatal errors), choose a disk, input speed and free space, and run the task.
Once you have initiated a task, you can view the current phase (e.g. analyze, defragment), action and file path, as well as completed percentage.
Furthermore, you can include and exclude certain items (extensions, file paths), move files or folders to the end of data, enable a log file and place it in the same folder as GUI, schedule a task and assign a username and password, as well as activate a screensaver installer and configure its settings.
You can also clean up the system (e.g. empty temp folder, recent folder, Internet Explorer cache), wipe delete data from the hard drive, set JkDefragGUI to run before or after a certain process has been initialized, and configure general options (e.g. enable to check for updates on startup, change interface language).
The program uses a high amount of resources when it is running a task, includes a complete help file and finishes a defragmenting job in a reasonable amount of time.
We haven't come across any problems during our tests and we think all users (both beginners and experienced ones) should test JkDefragGUI. It offers a simple and effective solution when it comes to disk defragmenting.
