About Defraggler

Defraggler is a disk defragmentation utility developed by Piriform, the same company behind popular software like Speccy, CCleaner Portable, and Recuva. This free disk defrag software allows users to defragment individual files, groups of files, or an entire disk drive to improve system performance by reorganizing fragmented data so that files are stored in contiguous sections of the disk.

Defraggler is designed to help improve the performance of your computer by optimizing the way files are stored on your hard drive. Over time, files can become fragmented, meaning they are split into different pieces scattered across the disk. This can slow down your computer because it takes longer for the drive to read these fragmented files. It helps by reassembling these pieces and storing them contiguously.

Here are some of its features:

Selective Defragmenting: Allows you to choose specific files, folders, or drives to defragment. This feature is useful if you only want to target certain areas of your disk.
Quick Defrag: Offers a quick defragmenting option that focuses on optimizing fragmented files without performing a full defragmentation. This can be especially useful if you're looking for a faster optimization process.
Full Drive Defragmentation: Can also perform a comprehensive defragmentation of the entire hard drive, optimizing the placement of all files and folders.
Schedule Defragmenting Time: You can set up scheduled defragmentation tasks to automatically optimize your hard drive at specified times. This helps ensure that your disk remains optimized without manual intervention.
Interactive Drive Map: An interactive drive map that displays the fragmented and defragmented areas of your disk. This visualization helps you understand the layout of your files and the effectiveness of the defragmentation process.
File Placement Optimization: The software allows you to manually move certain files to specific locations on the disk, potentially improving access times for frequently used files.
SSD Optimization (TRIM): While traditional disk defragmentation isn't recommended for solid-state drives (SSDs), this software includes an option to optimize SSDs using the TRIM command. This helps maintain the performance and lifespan of your SSD.
Detailed Reports: Provides detailed reports after each defragmentation session, showing the results and improvements made to your disk's fragmentation status.
Free and Paid Versions: The version with basic features is offered for free while a paid version is available that includes additional features and customer support.
User Friendly GUI: Includes an intuitive and user friendly general user interface that makes it easy to use, even for individuals who are not technically inclined.

It can also be made to run directly from removable media such as a USB flash drive making it a stand alone program.
You can follow these steps to make it portable:

Extract the files from the .exe to a folder on your USB flash drive using 7-zip.

Use Defraggler.exe or the 64bit variant from the folder on your USB to run the program.

Alternately, you can download this ready to use defraggler portable zip.
