TextAsset read non txt files

Found answer here: https://answers.unity.com/questions/1351604/is-it-possible-to-reference-a-custom-file-type-in.html

I guess my best solution is to rename these files to .txt

You can read files normally using System.IO.FIle class. You are not limited to any Unity tools for working with files. The TextAsset is what it says - an asset. It uses unity references, derives from UnityEngine.Object. It has nothing to do with file access, and it won't be present as a file in the build. The usual location for files that you want preserved in their original binary form in the build is the StreamingAssets folder. You can get the folder path by using Application.streamingAssetsPath and store any files that should be part of the build here. But you can also load any files from any location where the OS gives your app an access permission.

I use StreamingAssets for storing my custom config files and savegame files, and generally anything that can be changed during the game and written back to be preserved between app runs
