How do I specify C:\Program Files without a space in it for programs that can't handle spaces in file paths?

Question

A configuration file needs position of another file,

but that file is located in \"C:\\Program Files\",

and the path with space in it is not recognized,

Answer 1

No.

Sometimes you can quote the filename.

"C:\Program Files\Something"

Some programs will tolerate the quotes. Since you didn't provide any specific program, it's impossible to tell if quotes will work for you.
