What is .bak file and do I need it?

Nietzsche · Posted 10-18-2022 07:14 AM

I did the following code as shown in the video in the Programming 1 course and it created a .bak file replication of the excel file that I exported.

Do I need this .bak file? some sort of back up? Can I delete it or not create it in the first place?

It is a backup and you can delete it. Not sure if you can instruct SAS to not create a backup in first place.

Weird when I use same code and no .bak file was created for storm45.xlsx

So SAS just randomly create .bak file or is it based on some rule?
