@robnalexpress,

so far the folder has not replicate again, so I think that solve the issue. Once again, thank you for your help.

Hi robnalexpress,

thank you for the solution. I didn’t search for favicon.ico as I have theme folder replicated there as well. Most likely because everyone seems to have the default favicon.ico in the custom file list.
I guess search only works if you know what you are searching for.

Anyway, I will work with the custom file list and see if it stop the replication.
