Question How to delete all files of a file-type from cache?

Hi,
I've implemented an image downloader that stores jpg/pngs in "Application.temporaryCachePath". Now I want the option to clear all downloaded images again (without clearing the whole cache for the website).

I've tried "System.IO.Directory.GetFiles(@Application.temporaryCachePath, ".png")". That works when I run it in the editor but not in a browser. I assume this is the case because the files are not individually saved in the cache/indexdb?

So how can I delete all images instead?

Thanks

 

Not a solution per-se but just be mindful that the entire System.IO namespace won't work for web apps due to, as it says, being sandboxed into a browser and can't communicate directly with the OS.

I believe what you need to do is to look at either managing the indexdb directly or setup a backend service that can read/write files on your web server.

 

That's not true. I'm using System.IO to write and load files from cache and it works just fine.

 

Well, I stand corrected!

You're right, found this: https://forum.unity.com/threads/webgl-filesystem.294358/

TIL. Sorry I am not of much help though... Maybe manually handle it via external JS (https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API/Using_IndexedDB) ?
