How to import files from different paths

You could create a separate query for each file, or simply create multiple "Source" lines. Either way, just append all of them together in the end. Not sure I can be more specific. ImkeF might have some thoughts as well.

let
    Source = Csv.Document(File.Contents("C:\temp\powerbi\jobid.csv"),[Delimiter=",", Columns=2, Encoding=1252, QuoteStyle=QuoteStyle.None]),
    Source1 = Csv.Document(File.Contents("C:\temp\powerbi\months.csv"),[Delimiter=",", Columns=2, Encoding=1252, QuoteStyle=QuoteStyle.None]),
    #"Promoted Headers" = Table.PromoteHeaders(Source, [PromoteAllScalars=true]),
    #"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"JobID", Int64.Type}, {"Date", type date}}),
    #"Appended Query" = Table.Combine({Source, Source1})
in
    #"Appended Query"
