I once downloaded an app named "aFuel" from the German app store, but I don't have it anymore because over time I removed it from my phone and eventually reinstalled Windows. The app is no longer available (source).
How can I get this app back? (Or any app for that matter!)
I might have a PC backup that contains the downloaded app, but I don't know what to look for. If you can point me to a likely location on disk then I can look through my backups for any relevant files.
