Code reproducing the issue

viper.SetConfigName("testfile")
viper.SetConfigType("yaml")
viper.AddConfigPath("/dir/dir2/testfile")

Expected Behavior

When searching if file exists, file path should only be searched with list of available extension and custom extension if provided in config.

Actual Behavior

In line 86 in file.go , extension is not added while checking exists so incorrect files will be matched.

@sagikazarmark can you please check this?

Admittedly the "old" file search API is weird and not trivial to use. SetConfigType was never intended to be used as a file extension, rather an override and a way to set type information in cases where there is no file name at all.

The proposed fix would interfere with other supported scenarios though. For example, some people set the config name to .env and the type to dotenv to support reading from env files.

I would suggest checking out the newly released file search API in 1.20.0. At allows you to customize the entire file search process, while also gives you a much better default implementation.
