Building game deletes save data file - how do i keep the file when saving?

I keep a save data txt file in the data folder. I need to have this kept when i build the game. Help?

Simple just load/write your save from outside the build, e.g MyDocuments/UnityGameSaves/Save001.txt

Or even jsut make a folder called “Saves” outside of the builds Data folder, and put your save in that, you want to keep your saves out of the data folder.

Another but long and difficult way is to create a custom build editor script that loads all your saves, builds your game , then saves them all again.
