Samsung S4. Download whilst no Wi-fi and data connection off.

[AC Question]

I have a strange file downloading, which started when data connection was on. On turning it off, the download appears to keep going. Put into Flight mode, file continued to download. After a re-boot, still shows downloading.
The file appears as: fd91306d-7eb7-4643-8fa5....

Any ideas, please ?

Welcome to Android Central! I've seen posts about this, but I'm not sure what those files are about. Go to the App Manager, select Download Manager, and Clear Cache/Clear Data, then Force Stop. Does that stop the downloads from occurring?
