O&O Defrag offers various options for receiving further information about defragmentation. The tabs in the lower section of the "O&O Defrag" ribbon will help you switch between the categories explained below.

Progress

The progress bar illustrates recent actions you have run. For each drive there’ll be a brief summary displaying the results of any corresponding action.

History

Thanks to clearly displayed statistics, you can tell what effect a regular defragmentation is having on your system and you can track the success over weeks and months. You can monitor how many files have been sped up and how many excessive file fragments have been put together, for example. Based on the, you can then adjust your settings to match the defragmentation to your computer habits in order to get the best results.

Drive status

Displays information about the conditions of selected drives before and after defragmentation.

Here you can find information about your drive, the amount of space being used on it, and the file system. The refreshed pie chart will dynamically represent the proportional level of fragmentation during a defragmentation run.

The Status for the entire drive informs you about both the analyzed as well as the non-analyzed files and folders. A new evaluation occurs dynamically with each defragmentation.

File status

File Status provides an overview of the largest and most heavily fragmented files on your drive. The contents of this file system statistic can also be found in the status reports. You have to first analyze the file statistics of a drive in order to have them displayed here. This will occur after you click Analysis in the Ribbon bar.

Files can be listed according to various criteria with the Sorting drop-down menu.

Recommendations for your first defragmentation

The first defragmentation usually requires the most time because O&O Defrag has to check your entire system and move all files into their optimal position. This is especially the case with systems that have been in use for a long time and have rarely or never been defragmented.

The COMPLETE methods in particular are very time-consuming because the entire file structure needs to be optimized, which involves moving even files that are not fragmented.

We therefore recommend an initial defragmentation with the STEALTH or SPACE methods. These methods consolidate your hard disks very quickly and efficiently. Afterwards, you can use the COMPLETE methods for optimum performance or stick to the quicker STEALTH and SPACE methods. Whichever method you choose, your system will be significantly quicker than it was before!

Defragment Single Drives

  1. Select the drive you wish to defragment from the drive list.
  2. Clicking the Start button in the Ribbon Bar will start defragmentation using the OPTIMIZE default method. If you want to change this method, open the Start button's lower menu and select the Method you desire.
  3. Depending on the size of your database, defragmentation can take up to several hours. You can see the defragmentation in progress on the drive symbol and the status display.
  4. Once defragmentation is completed, you can have a detailed status report displayed as an HTML document in your web browser.

Defragmenting SSDs
When saving files, the controller of an SSD splits them into individual file fragments and then distributes them into the next free and "suitable" memory sections, called pages. This behavior can slow down SSDs because the individual parts must be found and the number of parallel accesses are limited. If the SSD is fragmented, it might require more memory cells because the system remembers how many fragments there were in the original file and saves them in this same number of cells, even if these files could fit into fewer cells. In the long run, this means being burdened with more memory cells than needed, which can lead unnecessarily to early failure of the storage device.

O&O Defrag offers the option of disabling shadow copies before defragmentation.

If you want to reactivate shadow copies after defragmentation, call up Run by combining the keys Windows+R and enter "sysdm.cpl" there, followed by Enter. Switch to the Computer Protection tab and then click the Configure... button. A new window will open with the Enable computer protection option at the top. Select it. Confirm the dialog with Ok. The shadow copies are now reactivated.

Defragment an entire computer

  1. To defragment your entire computer, select all the drives in the drive list. A multiple selection can be done by pressing Ctrl.
  2. If you click the Start button in the Ribbon bar, defragmentation with the OPTIMIZE default method will begin. If you want to change this method, first open the Start button's lower menu and select the Method you desire.
  3. Depending on the size of your database, defragmentation can take up to several hours. You can see the defragmentation in progress on the drive symbol and the status display.
  4. Once defragmentation is completed, you can have a detailed status report displayed as an HTML document in your web browser.

Defragmenting individual files and folder

You can also defragment individual files and folders. Just right-click the folder or file you want and select Defragment. O&O Defrag will be opened and the defragmentation begins. Defragmentation of smaller amounts of data is often completed within just a few seconds.
