VFB history settings. Amount of renders to be saved in history?

[vanderloo]

Can't seem to find where to set the amount of renders to keep in the VFB History. Also to save in the renderoutput folder.
Can this be done. I don't want 20+ previous renders saved.
VRay 3.0. Max 2015

You can specify an amount in MB. So if you set it to 2000MB and each vrimg file is 500mb, it will save 4 files
