How to delete everything at Application.persistentDataPath?

Questions & Answers
1

I’m saving some files to Application.persistentDataPath and now I would like the ability to clear out everything I’ve saved there at once. What’s a good way to go about that? Also is there anything else stored there automatically that I should be aware of, maybe something I wouldn’t necessarily want to delete.

Thank you!

I think you can use this.

 foreach (var directory in Directory.GetDirectories(Application.persistentDataPath))
                {
                    DirectoryInfo data_dir = new DirectoryInfo(directory);
                    data_dir.Delete(true);
                }
    
                foreach (var file in Directory.GetFiles(Application.persistentDataPath))
                {
                    FileInfo file_info = new FileInfo(file);
                    file_info.Delete();
                }

On my project I tried writing an editor script to delete the contents of persistentDataPath, like this:

DirectoryInfo dataDir = new DirectoryInfo(Application.persistentDataPath);
dataDir.Delete(true);

However, I got an IOException with a “Sharing violation” message. I think this is because another editor script has some file within persistentDataPath open, and so it cannot be deleted.

So, I think the only way to properly delete the persistent data path is to close Unity3D and then use your operating system to delete the folder. On MacOS, this is ~/Library/Application\ Support/vendor/title/ and on Windows it is a similar path under your AppData\LocalLow folder.

You can try to create a new file directory
Directory.CreateDirectory (Application.persistentDataPath + “FilesToDelete”);
Save the files you need to delete into the newly created Folder, then use
DirectoryInfo dataDir = new DirectoryInfo(Application.persistentDataPath + “/FilesToDelete”);
dataDir.Delete(true);

Hope this helps!
