new doubt. .sl files

If I import a file to Identified .sl, and inside that folder there are files. Deletes and replaces that brings .sl file, or combines there but what adds the .sl

Not sure what you mean here exactly but a .sl file is a just a .zip renamed to .sl. If you were to rename it to .zip, you could unzip it and see it's just a zipped folder with the sorted .txt files.

I'm not sure exactly what you're asking though, this isn't clear, "Deletes and replaces that brings .sl file, or combines there but what adds the .sl"

If I import a verified .sl to the folder is added to the files that are already, or replaced

It is added to the files, not replaced.

thanks!!
