steam and sh3

Hi myxale
thanks for your reply. Am sorry because i wasn't clear enough when posting. Firstly i d/l the game and it was created folder at c\programms (x86) steam...
Then i thought that in the future i will need the original files and went back to steam and asked for a backup. i followed instructions and created a folder called "silent hunter iii" and inside there were 3 files
1/ ....csd 1,8gb~
2/.....csm 800kb~
3/....sis 1kb
and i don't know what program to use for opening or for installation.
Also i made a search at steam's forums and i read that some programs such as antivirus and specially " iobit advanced system care* " that i have and here its them recomendation

"* We recommend that applications listed in bold with a ( * ) symbol are fully uninstalled from your system if disabling them does not resolve the issue".

Whats your opinion to uninstall advanced system care-create a new game back up and installation the application again?

thanks
