Defraggler-Specific Reports:

These reports are specific to defragmentation in CCleaner Network Professional:

  • Management Reports - Defrag scores
  • Technician Reports - Most fragmented, Oldest defragmentation

The Audit Scores and Oldest Audit reports also take defragmentation into account when calculating endpoint health.

Running Defraggler:

There are two steps to defragmentation: analysis of the drive, and the actual defragmentation.

Note: Do not defragment solid state drives, as doing so will be ineffectual and may cause damage to the drive. This procedure is intended only for use on conventional hard drives.

Analyzing a network, group, or endpoint for fragmentation

  1. In the Network Tree, right-click the network, group, or endpoint, point to Defraggler, and then select Analyze system drive(s).
  2. If you are prompted to confirm, select Yes.
  3. When the analysis completes, the result is shown in the Network Health section of the right pane as the Defrag percentage.

Defragmenting a network, group, or endpoint

  1. In the Network Tree, right-click the network, group, or endpoint, point to Defraggler, and then select Defrag system drive(s).
  2. If you are prompted to confirm, select Yes.

Note: You can defragment without manually analyzing first, but you won't get a chance to review the files or fragmentation level before Defraggler runs.

Defragmenting specific files on an endpoint

  1. Run the analysis above for a group or endpoint.
  2. In the Network Tree, select a group or endpoint. In the right pane, select the Defraggler tab.
  3. If you selected a group, select an endpoint in the endpoint list in the right pane.
  4. Select a drive (the default is C:).
  5. Select View Files or the File list tab.
  6. You can select one or more files by using the check boxes (or select the check box next to Filename to select all files).
  7. Select the Defrag Highlighted button.
    > To make it even easier, once you reach step 4, you can simply right-click a file and then select Defrag Highlighted.

Other right-click options in the file list:

  • Defrag checked - defragments files you have selected using check boxes.
  • Check highlighted - checks boxes for files you have highlighted.
  • Uncheck highlighted - removes check boxes for files you have highlighted.
  • Highlight folder - if you have highlighted a file, you can use this option to highlight everything in a folder, parent folders, or drive.
  • Save list to text file - saves the names and details for all files on the Endpoint to a text file.


You can schedule Defraggler to run once, daily, weekly, monthly, or on boot-up for an Endpoint, group, or Network.

If possible, schedule Defraggler to run in that endpoint’s off-hours (for example, in the evening, off-shift, or on the weekends, depending on the work schedule). However, please note that the computer must be turned on in order for the scheduled task to run.

Scheduling Defraggler

  1. In the Network Tree, right-click an endpoint, group, or network, then point to Defraggler and select Settings.
  2. In the Defraggler settings window, select Enable scheduled defrag.
  3. Choose the drive to set a schedule for (schedules may be set independently per drive).
  4. Select the frequency to run Defraggler, and specify any additional settings.
  5. Select OK.

For scheduled defragmentation, the Task Scheduler service must be running on the endpoint.
