Handbrake - Files overwriting each other.

Hello,
I'm doing a tutorial about HandBrake. It has been working well for me.

For the sake of the tutorial, I uninstalled it and then recorded as I installed HandBrake. After the encoding, there is only one file. The files are overwriting each other.

I would then select five files and run those through HandBrake.

What settings do I need to change so the files will not overwrite each other?

Thank you

I fixed it. I clicked 'reset'
