(on Android) I can't seem to find the install dir. Usually, apps are installed in "Main storage/Android/data/"
When I install an update for a VN, I manually copy the saves to a temp location, and insert them again. I can't really do that here. Probably it's installed in data, but with a generic name I won't spot, or know to search for :(
No I use a third party file browser, standard android apps do not give you access to the filesystem.
My fault though, the "Android\data\santa.lucia\" folder is not generated before you create a savegame file, and I hadn't done that on this install (I forgot).
I know I could just install it on top of the existing, but that doesn't always work, and I wouldn't recommend it.
Thanks anyway :)
Mobile apps are designed as complete packages, not as incremental updates. I would never install an application on top of an older version, as you don't know which files are kept, and which files are replaced. The creator must really be vigilant when creating a new installer, and mistakes happen. Obviously, we don't reinstall windows whenever there's a new update - which is every 5 minutes these days, but that's created differently. To give you another example; When you update your GPU driver, you would prefer the "clean install" option, to make sure all relevant files are updated, and no bad mix of old and new files exist.
Since I can't be sure.. I'll always remove the app, before installing a new version.
Often, removing it will not removed the save game folder, but sometimes it will.
That's my opinion anyway :)
