How do i read stuff from a config (.cfg) file?

[zero]

I would really need to read some stuff out of another application's config (.cfg) file in my application. How do I do that?

Do you know the format and fields of the config file?

I'll give you advice: "File extension isn't so important, that data inside file" besides basing on file extension you won't ever know if file is this file, that you're thinking

The line I would need looks like this:
"value" "25"
I would also need to save this line into the cfg file after modifying, because other applications also use this file.

You can use a TStringList to read the file, pharse and change the content, and save it back.
