everytime I make a replay I have to save it in the replay section and right now I have like 100 of my replays in there can anyone help?

By posting do you mean saving a replay that you want to keep?

You are able to take replays in/out of your toribash file by going to the "replay" folder.
If you save a replay it will automaticly be sent in that folder. It cant be directed to a different folder as far as I know. If you want to take replays out or put some in you will have to manually delete/copy them.

You can use the autosave function to attach replays you don't want to save, just look for the most recently created file and/or use the names of the players involved to locate it.

You can also delete replay files or move them to the autosave file if you no longer wish to have them cluttering up your ingame replays section.
