writing user accessible files on ios/android

How can I write say text files on a android and iOS app which the user can then open and read? Say I write a csv file or a image and want the user to be able to view them, where do I find the path in Android and iOS to do this?
Thanks

 

You can write and read files here:

https://docs.unity3d.com/ScriptReference/Application-persistentDataPath.html

 

This is completely outside of Unity.

It will be different for iOS and Android. The details will be on the developer sites for each OS.

It will involve least some combination of the following:

- determining what kind of file you want (photo? text? PDF? other?)

- determining if the user has an app that can open that installed or not

- determining where that app expects to find documents

- determining what permissions your app must have to write the file (different for each of the above)

- possibly other permissions and/or metadata that needs to be told to the OS so it can open those files outside of your Unity program

If you just want to persist stuff to disk and open it later in your program, the link above from Praetor will let you write/read those files, generally speaking.
