ROOT

Dear rooters,

it seems that maximum size of a TFile is about 1.8 GB. Is it possible to increase this size?

thank you,

There is no limitation for the file size,. It can be as large as your system permits.
By default, ROOT Trees have a maximum size of 1.9 Gigabytes. You can change this default by calling TTree::SetMaxTreeSize
