what is the significance of the defaultfileextension then.

[deryrahman]

Just checked that,DefaultFileExtension is used to define the type of parser.

For example, we have config yaml config file, but the name is optimus.custom. So we can use yaml parser to parse file optimus.custom

DefaultFilename       = "optimus.custom"
DefaultFileExtension  = "yaml"

hmmm the salt config says filename without extension and it was working without file extension as well. but only when both file name with and without extension present it is loading the file without extension.

yes, I think what it says is different with the source code here, hence there's a mismatch
