HoloLens 2 UE4 Persistent Save #17

Open bvaibhav1 opened 1 year ago

bvaibhav1 commented 1 year ago

Hello,

We are downloading some data in a UE4 Hololens 2 app, and saving it to FPaths::ProjectSavedDir(). However this folder gets deleted on app install and uninstall.

Is there a mechanism/example to save the files to local app data or some other folder to keep the files even after Hololens app is uninstalled.

HoloLens apps, being UWP, have special restrictions about where they can read/write. This is a good guide: https://learn.microsoft.com/en-us/windows/uwp/files/file-access-permissions. Looks like you may be able to write to the user's Downloads folder. There are a few other options there.
