DLP Network Discover Scan excludeFiles

Hi, I would just like to know the proper syntax of excludeFiles filename.txt when the content root is in IP address (e.g \\192.1.1.1\C$)

I saw in the admin guide that the filename should be the same as target scan in the content root.

I tried this one 192.1.1.1.txt but it's still not excluding the directories in the text file.

Hope someone can help me on this.

Note: I do not want to use the exclude filters in the console as it has limitation of 1024 characters only and will not fit on our requirements.
