Automation folder exclusions allow you to specify folders that the Automated investigation will skip.
You can control the following attributes about the folder that you'd like to be skipped:

Note
At this time, use of wild cards as a way to exclude files under a directory is not yet supported.
Extensions of the files: You can specify the extensions to exclude in a specific directory. The extensions are a way to prevent an attacker from using an excluded folder to hide an exploit. The extensions explicitly define which files to ignore.
File names: You can specify the file names that you want to be excluded in a specific directory. The names are a way to prevent an attacker from using an excluded folder to hide an exploit. The names explicitly define which files to ignore.
