How to save a text file to relative Path

Question

I'm creating an app that should be accessable from every platform (android, IOS, windows). At this moment I'm saving a file that is set to a specific path. c:\test\test.exe. Now I know that Android and IOS don't have such directory. I was wondering if it was possible to save the file to a relative path? If not I might have to adapt the code that checks on what kind of device the app is running

psuedocode:

If runningOnWindowsOS writefile(c:\test\test.txt)

if runningOnAndroid writefile(NOCLUE)

If runningOnIOS writefile(NOCLUEEITHER)

this is my code at the moment:

        string path = @"C:\test\test.txt";

        string createText = txt3.text + txtToLog + System.Environment.NewLine;

        File.WriteAllText(path, createText);

any clues on how to proceed with this

Answer 1

Utilize Unity's persistentDataPath.

Contains the path to the game data folder (Read Only).

This is path is platform specific.

Answer 2

I had had some problems with Loading of Json file from persistentDataPath and dataPath, so if you will have a problem like that - another solution is to write and load files from Resources folder that is Resources - it also allows you to load and write files and even specify a type of the file loaded Load.

Note: remember to use forward slashes - all Unity assets use them.
