This is actually IIS folder (Microsoft Internet Information Services). Here is a guide how to deal with the logs:

It's usually safe to delete logs in the inetpub folder. In fact, any folder with logs that aren't transaction logs can be cleared. I wrote a script that will clean all logs for exchange 2016, assuming default locations.

Have you enabled circular logging, or are the log files allowed to grow without limit?

If circular logging is enabled the log files will grow only to the maximum size permitted and from that time forward new entries will overwrite the oldest ones.

I'd follow the Dr Klahn advice,
Just enable the Circular Loggin, and then disable it.
but sometimes a great amount of logs means that there's probably something wrong on the server so I'd check it out event viewer to see if there are any issues I could solve it.

And windows backups truncate the logs and clears them, same as backupexec solution.

From your screen shot that is the IIS Log file folder. Yes you can delete those files without any issues. Circular logging will nothing to do with the IIS Log files, so you are fine to delete them. I would suggest looking at the below link and running the script as a scheduled task because it will clear the IIS Log file and also the ETL log files. If not this will be an on going issue for you. I run this script once a month, but you can run it more frequently if you need to.


Thanks to all for guidance.
