I'd like to share the steps to add a custom rule to CCleaner to clear the files generated by Processing 2.0 each time it runs a sketch. If you run many sketches, the number of leftover files on your disk can quickly accumulate. This description is written for Windows 8. The same technique can be used for other systems, although the specific folder locations may vary. You can download and install the free disk cleaning utility CCleaner from here.


Setting up the rule

1. Create a new text document on your desktop (because of protected folders in Windows 8).

2. Rename the file to: Winapp2.ini

• Make sure you can see file extensions, so the file is not named Winapp2.ini.txt
• Choose yes to change the file extension.

3. Right mouse click on the file and choose Open With... then select Notepad.

4. Copy-paste in the following text where the yellow file location points to the correct file on your computer!

• Note that FileKey3 clears all the files and folders in the Local\Temp folder including those that are not related to Processing! However since these files are also leftovers, this is an added benefit.

1. [* Processing]
2.  
3. LangSecRef=3024
4.  
5. DetectFile=C:\Coding\processing-2.0.1-x64\processing.exe
6.  
7. Default=True
8.  
9. FileKey1=%userprofile%\AppData\Roaming\Processing\console|*.*
10. FileKey2=%userprofile%\AppData\Roaming\Processing\debug|*.*
11. FileKey3=%userprofile%\AppData\Local\Temp|*.*|RECURSE

5. Save and move the file Winapp2.ini from your desktop to CCleaner's installation folder.

• The default installation folder is: C:\Program Files\CCleaner

6. On Windows 8 these folders are protected, so - when asked - choose yes to move the file into the folder.

Testing if it works

1. Run CCleaner and choose Analyze.

2. If there are any files found for this rule, you should see an item: Utilities - *Processing

3. Double click the item to see the found files for this rule.

4. The first time there are probably some / many non-related files from the Temp folder.

5. If it's correct press Run Cleaner to remove all the crap files from your computer!
