Retain file name column when using Folder as a data source - Power Query M
Actually, it's pretty easy with this line of code:
= Table.AddColumn(Source, "Custom", each Table.PromoteHeaders(Csv.Document([Content],[Delimiter=";", Encoding=1252])))
Replace your Step 2&3 with it.
It will retain all the metadata from the 1st step and add the content in an additional custom column.
If your csv's have all the same headers, you simply expand this column and the headers of the 1st file will be shown - and expand all other files on these cols as well.
If there are differnt cols - just come back & I'll post the code for the auto-expand of different headers.

I am using the folder type for get data, how can I show the file name or file create date for each row of the merged data?
