      Description

      I was doing a bit of reading to learn if there is a file/tree size limit for ROOT I/O. A sentence under the "Adding a Branch to an Existing Tree" section here: https://root.cern.ch/doc/master/classTTree.html mentions a 2GB tree size limit. Since I've been creating trees larger than 2GB I wondered if I was entering some kind of unsupported realm, some more reading lead me to here: https://root.cern.ch/doc/master/classTTree.html#a4680b0dfd17292acc29ba9a8f33788a3 - some function which appears to allow the max size to be user defined with a default at 100GB. I assume this is the current behavior, but just wanted to mention the mismatch.
