Answered from the vendors’ own pages
FreeFileSync: Is FreeFileSync free?
Yes, open source and free. A paid Donation Edition adds convenience features such as parallel sync and portable installs.
CCleaner: Is CCleaner free?
There is a free version, with a paid Professional tier adding scheduled cleaning and real-time monitoring.
FreeFileSync: Is it a backup tool?
It synchronises folders and supports versioning, which covers many backup needs, but it is not a managed cloud backup service.
CCleaner: Does registry cleaning actually help?
Very little on modern Windows. The measurable gains come from clearing caches and controlling startup programs, not from the registry.
FreeFileSync: Can it sync to cloud storage?
Yes, including Google Drive and SFTP or FTP targets alongside local and network paths.
CCleaner: Is CCleaner safe?
It is a mainstream product from Gen Digital, though a 2017 supply chain attack distributed malware via an official build. That was resolved, and it remains a fair reason some administrators avoid it.
