Running CCleaner in debug mode means you can view a detailed log of CCleaner's activities. This can help you with troubleshooting. CCleaner also creates a log file in the CCleaner install folder.

Run CCleaner in debug mode in 4 steps:

  1. From the Windows desktop, click Start (in Windows 7) or right-click Start (in newer versions of Windows), then click Run.
  2. In the Run dialog box, type <path to CCleaner> /debug. Typically, this will be:
    "C:\Program Files\CCleaner\CCleaner.exe" /debug
  3. Click OK. CCleaner starts in debug mode. You will see the word  [debug] next to the version number at the top of the program window.
  4. Once you have finished using CCleaner as usual and have quit the program, use Windows Explorer to navigate to the installation path (the same path you typed in Step 2). The log file will be in this folder in the format: CCleaner_log[date].txt.

CCleaner may also be used via the command line, and you set it to save a log of the analysis or clean function performed.
