ccleaner cleans both discs?

CCleaner for Windows
1

Simple question:

I have just added an SSD and installed it additionally to the HDD (which was formatted completely).

CCleaner is newly installed on the SSD and I wonder if running it now, will clean both discs?

Or do I have to install it on drive E also, and run it there separately?

Thanks

Wherever it is installed CC will only run against your system disk, unless you have specific includes pointing to your other disk(s). CC only needs to be installed on one disk
