Time to cleanup the root directory. A long time ago I upgraded from 2.3.6 to 3.0 and I think there are some folders left from 2.3.6 that should be safe to remove by now. Any pointers on which folders can be safe to remove?

 

 

You can compare the file set from the version you are on and delete anything that isn't current. Always take a backup too.

This would vary depending on what version you have though.

IPS4 file system is almost all new, so you can really clean up if you are ion 4 now. 

Yep, I just thought of that
