Get repeater area to save data correctly

I have configured repeater area in my form to multiply fields and save them to the db.
Somehow Save Data action inside Loop Event saves the whole repeater area data into one line in the table. 3 days struggling and trying every advice from forum and FAQ. Please show where I did a mistake.

FACEPALM😡😫😢

Hi!. I need your help!
How do you get the name of the model "Files"?. I have the "repeater area", the "loop event" and within it the "save data" but I don't know what the "data provider" of the "loop event" is.

Model name "Files" placed in "repeater area". Loop event takes data of the model "Files" and run thru it saving each record

Thanks to your post and your answer I managed to solve my problem. It was perfect !. You're the best. Greetings from Argentina!. Thank you very much!.
