Include .sol Extension in File AddZone Subtext

[a-ridley]

Problem

The File AddZone tells me I need to add the solidity source files and metadata. This may have some developers question which solidity source file is wanted here.
Could it be the .bin? or the .json? or the .sol?
Are they all valid?

Solution

Add the file extension (.sol) in parenthesis to the subtext to clarify
or add the extensions of all the files that are accepeted
