Done. I've included the Code Cache folder in my Custom Clean.
I had 2 concerns with that folder not being cleaned:
- the size and number of files
- the links of your visited sites which were in the javascript code
Thanks for your tip
I've just realized that Ccleaner does not delete the files stored in C:\Users\xxxx\AppData\Local\Google\Chrome\User Data\Default\Code Cache\js
All the other Google cache directories are cleaned. I 've found more thousands of files stored there
