Cleaner One has a smart uninstaller which allows the user to delete leftovers of an app more thoroughly right after the user moves it to Trash.

To use this feature, do the following:

1. Move the application you want to uninstall to the Trash. A pop-up window will appear asking to delete the leftover files.
2. Click Deeply Uninstall.
3. It will display the saved disk space. Click OK.

Find and delete big files on your Mac to free disk space. Do the following:

Some files or folders may be locked. Since Cleaner One is a sand-box app in the Mac App Store, Cleaner One does not have permission to access locked files or folders.

• If a folder is unlocked, unlocked files in the folder can be deleted, but locked files cannot be deleted.

   You can double-click the folders to browse or check the files.

4. Select the folders or files you want to delete, then click Remove.
5. Choose between Remove To Trash or Delete Permanently, then click Proceed.

To use the Deep Disk Clean feature, do the following:

3. The window will display all the junk file categories and by default, it only cleans Application Caches and Application Logs. Select other items that you want to clean, then click Remove.
4. Wait for your Mac to be cleaned.
