Choose files you don't want to clean with CCleaner for Windows

This page explains the Options > Exclude part of the CCleaner app and how to use it. 

What excluding a file, folder, or Registry Key means:

You can choose specific files, folders, and Registry entries to include or exclude when CCleaner cleans. If you add something to Exclude, that file or Registry entry never gets cleaned despite what you select elsewhere in CCleaner.

How to exclude files, folders, or Registry Keys from cleaning:

In CCleaner, click the Options icon:

  • Click the Exclude button
  • Click Add
  • Work with the Exclude modal window as follows:

Using the Exclude modal window:




To choose a drive or folder to exclude, select Drive or Folder, click Browse, and then click the folder or drive.

To choose a file to exclude, select File click Browse, and then click the file. You can only add one file at a time.

To choose a Registry entry to exclude, select Registry Key, click Browse, and then enter the full path to the Registry key.

Note: For each of these, the desired path may be copied and pasted into the field to the left of the appropriate Browse button.

File Types

This selection is only relevant when you have selected Drive or Folder.

By default, CCleaner will exclude all files in the selected drive or folder. You can choose to exclude only files of a certain type. To do so, click File Types: and type one or more file extensions. For example,

*.doc to exclude all .DOC files

*.exe;*.bat to exclude all .EXE and .BAT files

Note: In Custom Clean and the Registry Cleaner, you can add individual items to the Exclude list by right-clicking on the item and then clicking Add to Exclude List.
